The difference between a teacher and a GREAT teacher is that the GREAT teacher makes a complex subject so simple that one remembers it for entire lifetime without much effort. Jesse Mason is without any shadow of doubt a GREAT teacher.
@@JesseMason"Two parallel conductors, 20 Ohms being the resistance of each, are binded to a source of emf=120V and internal resistance 10 Ohms. The free ends and the middles of the two conductors are binded together with two lightbulbs, each of 200 Ohms resistance. Find the current passing through the source." This is in my textbook and they say it's I=0.89A. I was using this exact method to solve it and I don't see how that can be. I'm so confused. I would naturally assume it's a mistake in their solutions, but they even drew the circuit AND my solution is too far from 0.89A, namely 3.999A.
@@JesseMasonAlso, if you could explain why parallelly tied resistors offer less resistance than each individual one of them, that would be great. Like if you tied 15 of 2 Ohms each in parallel, the total is just 2/15 Ohms. I am really confused as to why that is, can't really visualize it. Like, there are smoke pipes for fire house heaters that look like so: one pipe dividing into severall narrower ones and that after half a meter merge into a single one as wide as before the splitting. I'm sure you've seen those, they're called "savers" where I live, and their purpose is to slow down heat and "save" it within the room for longer than it would stay in the single wider pipe. It looks the same as a parallel circuit, and yet parallel circuits have the opposite effect. For electricity, parallel means less resistance, while for smoke and hot air it means more, and I am really confused as to why the former. It's so counter-intuitive.
There are some who are incredibly smart, BUT they either (1) want to show off how smart they are and talk in hieroglyphics or (2) don't know how to explain in simple terms a complex situation. End result, they can't teach for sh*t. Then there are those who are smart or have long experience but can explain a complex situation to the average Joe walking down the street. They are the TRUE teachers, they are rare & gifted. Jesse Mason is one of the gifted.

I have seen A LOT of videos on youtube BUT this is literally the ONLY video that REALLY made me understand the whole lesson. THANK YOU SO MUCH FOR MAKING MY LIFE EASIER!!! God blesses you.
Went through multiple videos to learn resistance across triangular structure, but understood very little, this was exclusive and finally useful. May allah reward you with abundant goodness in your efforts.
You're the man Jesse!!. I was understanding the theory but found myself getting lost in the more complicated circuits. Your method of breaking it down and going from left to right with the junctions marked is flippin fantastic and helps to make everything clear so there's less chance of messing up
Wow took me 14:05 minutes to understand what he said.. you won’t believe I’m taking a course for the LADWP & they have a video 30minutes long the professor in the video made 3 mistakes trying to explain the same thing I just saw & im so glad I found this video … thank you so much Mr Mason 🙏
Nope ... if you use Kirchhoff's Voltage & Current Laws (KVL & KCL), with simultaneous equations, you get the voltage and currents across all segments simultaneously. There are no "redraws" involved ... so it scales well for more complex circuits (the real world). Imagine two of these problems on a 30 min test. This lecture was a good insight into equivalent circuits, if asked to reduce to that (i.e. reduce to Thevenin equivalent) ... but the "go to" method is voltage loops (KVL) and current nodes (KCL) simultaneous equations. I remember having to incorporate mutual inductance & capacitance ... and it mapped easily with simultaneous equations.
OH MY GOD!!! Thank you soo much!! I always found it confusing on how to break down and build a circuit but now i can do it easily!! THANK YOU SO MUCH!!! Loads of Love from INDIA !!
You have no idea how much this helped me. I have an exam for physics in a week, so I sat down to study for it by looking at the previous exams. There was a problem similar to this but with the battery in the middle. I had no idea how to work it because my Professor assumes that we know how to draw these circuits and know what a diagonal wire is supposed to when he's only given us problem with them blatantly in series or parallel. I sat a solid hour trying to figure out the question, and then I just gave up and tried to see if anyone has solved the problem on the internet. It led me to this video, which is by far way more valuable than knowing how to solve the problem. I actually know how to do the problem step by step now and this video made it much easier for me to understand. I wish you were my professor ;-;.
I went through several videos, and this one was the absolute easiest to understand. It is a long way to do it, but it will keep you from making mistakes. Leaving some extra space and going back to the redraws saves some time....great job!

I've been doing this type of math for quite some time (36 years) but I really like the way you went through this. I helped a student with this type of reduction method today - and even thought of calling it Break it down and build it up - and he loved it. I will point him to your video for an even better explanation.
This is the best video I have seen on finding equivalent resistances from complex looking circuits. I now understand how to simplify these complex circuits by redrawing them in an easy to understand way.
THANK YOU SO MUCH! I'm working through electrical engineering and I was absolutely stumped on my assignment. The break down and build up method clarified it all. Man, I can't thank you enough!
Heres a little story I made up to remember the rules of series and parallel circuits. Its incredibly cheesy. Once upon a time there was a parallel player. He hit up all the women with the same line.... voltage. Since he had so manny women to go to he didn't face much resistance. only problem was he had to divide up all his currency amongst all of them. After playing the field he got into a series of serious relationships. Since the woman were more traditional each one gave him her full resistance. To show that he was a one woman at a time man he gave each his full currency. He even dropped some voltage at each one until finally he spent the last of it at the last one. Hope this helps at least one person out there.
I’m about to take my physics final and kept getting the Req barely wrong on the complex circuits. This video saved me, this makes it so much simpler. You the man

Hi Josh. Great question - and I've received many criticisms about that dummy resistor... If you have done a few of these circuits before, you'll probably know right away that j2 and j3 are one and the same junction because a 0-ohm wire unites them. Not all newbs see that right away though so I incorporate the dummy resistor to 1) visually demonstrate the logic of uniting the junctions separated by a wire, 2) make the translation from the given circuit to the first redraw crystal clear, and 3) highlight the assumption we're making about the resistance of our wire, which is simply not true in the real world. Hope that answers your question, Josh. Cheers from Detroit!
Jesse you just gave me back most of my confidence that was shattered over a weekend of trying and failing on repeat. I will be trying this out before class tonight, and will let you know how it goes. Possibly the first time I have ever "liked and subscribed" to any UA-cam video, ever. ✌🏻
I did these types of things when I was in school and never understood them. I was a Chem E so I never used what I learned. Just intrigued and found your explanation to be great. Thanks.
Anthonia Grace damn! ok, so I was takin a night class in college at the time which met once a week so technically we covered it in one night. yesssss I beat you! my life is now complete lol... wheres the noose?
My concepts aren't clear , so i did'nt understand any other videos but yours i understood it with no problem . One of the best videos in the youtube yet , my words aren't enough to complement you ❤❤.
Thanks a lot for this video, Jesse. This is really helping me a lot. The problem I encounter is keeping track of the parallel resistors that I have turned into series resistors. It's not that much of an issue with smaller problems but in the future, when I'm dealing with 14 or 15 resistors, I know it's going to be a headache.
very well explained. I wish i would have found this Video sooner, because this was the exact same electrical circuit i have had in my last recent exam🙃😆
The gift of being able to effectively communicate understanding is the power of true knowledge and wisdom. Thanks for going over this, it’s hard to find “teachers” of these things who can effectively make a topic digestible.
Electrical engineering student here. I've been studying circuits for a while now, and I've never seen it explained so well. Also, I believe that this is the first time that I've seen a 0 ohm resistor added to circuit. That idea could have saved me so much time on circuit homework/tests. In your opinion, can this concept be used when solving for the transfer function of a Laplace Transformed circuit?
Best explanation! I found this about 6 years ago. Now I have to do this problem again in a test. And I could not remember the video and it just popped up in my feed this morning! Thanks again 👍🏻
Since this is so easy, apply and demonstrate this method to the 3-dimensional cube, where every line represents a 1-ohm resistance. 8 junctions in all, and the power is connected diagonally
its so simple, best for beginners. i am taking civil engineering but somehow have basic electrical engineering course and literally having hard time understanding this. thanks you saved me through semester.
how do you find the junction...? what if there is a juntiom where all resistor connect together?? how do we need to differentiate whether it is parallel or series??
Jaymee Ong Bro, i am subscribed your channel and watch all the video and also like on the video. So please you are also subscribe my channel and watch the video,thanks for subscribe my channel
It's the dummy resistor step... that should have been a parenthetical comment... I took it too far. Sometimes I take things too far. Like this comment. I should've just thumbs-up'd your comment or said thank you... but I feel like I need to defend my teaching abilities from five years ago. So I make a long-winded reply no one will read deep in the comments section. Phew. Glad I got that out of my system.

Jesse you just gave me back most of my confidence that was shattered over a weekend of trying and failing on repeat. I will be trying this out before class tonight, and will let you know how it goes. Possibly the first time I have ever "liked and subscribed" to any UA-cam video, ever. ✌🏻
That's great to hear, Matt. How did it go?
the best ever learning videos I watched .. maybe late.
Thanks, Akhil!
hey dude, I am in class 10th and preparing for my boards! i was not able to solve this kind of question but now I am, RESPECT LEVEL ++ FOR YOU 😉😉
I lost it at 5:08. Great video dude! 6 years and people are still finding this useful.
I hope the utility of my work outlasts me. Cheers, Tom!
Thank you so much. My 14 mins of watching this video wasn’t a waste.Fantastic work, well explained.
Sir from now on, I'm a fan of yours from India now my concept is 100% clear
Thanks again and love from India
Found the masterpiece after so many hours ❤
I did these types of things when I was in school and never understood them. I was a Chem E so I never used what I learned. Just intrigued and found your explanation to be great. Thanks.
How? How the fuck did Sharma ji ka beta fail to understand something? You must be adopted
@Sawantar jain
🤣🤣🤣🤣😂😂😂😂
2-4 months of college in one vid xD great job
+David Saez Nice! Thanks, David.
+David Saez y class covered this in one week...
+HGOD 45 My Highschool class covered it in 2 days; (
Anthonia Grace damn! ok, so I was takin a night class in college at the time which met once a week so technically we covered it in one night. yesssss I beat you! my life is now complete lol... wheres the noose?
HGOD 45 Nice! Unfortunately I still don't understand it and finals is tomorrow :(
My concepts aren't clear , so i did'nt understand any other videos but yours i understood it with no problem . One of the best videos in the youtube yet , my words aren't enough to complement you
❤❤.
Thank you so much! I've learned more from you in 14 minutes than my physics class in a semester.
.. the maths involved is less than one minute.
(forget the redundant 'fake' resistor) - how many redraws? Seriously?
Thank you for helping me and my classmates through our electric circuits class in college.
I've struggled with these kinds of circuits for a long time, finally got it after watching this trick, thanks a lot!
Music to my ears! Thanks for sharing.
Thanks a lot for this video, Jesse. This is really helping me a lot.
The problem I encounter is keeping track of the parallel resistors that I have turned into series resistors. It's not that much of an issue with smaller problems but in the future, when I'm dealing with 14 or 15 resistors, I know it's going to be a headache.
Good luck to you, Micah!
very well explained. I wish i would have found this Video sooner, because this was the exact same electrical circuit i have had in my last recent exam🙃😆
lol
Thank you! I couldn't understand circuits at all and you just blew my mind with ur method!
Wish I knew about your channel when learning about circuits for the OAT exam! Well explained! Now this is helpful with my Arduino hobby
I am gonna say, for me it is most useful video of 2019 :)
The gift of being able to effectively communicate understanding is the power of true knowledge and wisdom. Thanks for going over this, it’s hard to find “teachers” of these things who can effectively make a topic digestible.
Electrical engineering student here. I've been studying circuits for a while now, and I've never seen it explained so well. Also, I believe that this is the first time that I've seen a 0 ohm resistor added to circuit. That idea could have saved me so much time on circuit homework/tests. In your opinion, can this concept be used when solving for the transfer function of a Laplace Transformed circuit?
Hi Franklin - not sure about LT circuits... would have to revisit them to say for sure.
Wow, such a great teaching!
I am now familiar with these types of questions. Thank you so much sir ❤❤❤
This online tutorial really help to understand the concept on Electric Circuits. Please I need more and I'll send some questions .
Please do more circuits like this. It was great!!!!
Why he doesn't use Wheatstone bridge?
"Let's break it down now. Break it down now!"😂
This is the most useful video I've ever seen.
Best explanation! I found this about 6 years ago. Now I have to do this problem again in a test. And I could not remember the video and it just popped up in my feed this morning! Thanks again 👍🏻
That’s awesome! So glad you found it helpful twice!! Hope you crushed the test. Cheers from Detroit!
Absolutely amazing video. Having to do one of these as a Chemistry major, not an EE major. Saved my butt a lot of time tonight for sure. Thanks!
Bro.. I am going to ace tomorrow's quiz because of this video. Really WELL DONE MAN. * Starts to clap slowly *
*slow bow* Hope you crushed it, Omar!

بشر كيف سويت :)
bruh i just started my second sem of engineering after 0 studies during the pandemic, this really helped me jump back up. thanks u teachh
1:35 am I the only one who laughed at that.. haha. "break it down now!" :)
=)
No...you are not alone!😂
5:08
Me too!!
Thats 1:34 ohk human error
I love your enthusiasm
+Garry Superales Physics fires me up, Garry.
I love physics too!
Thanks Jason. it is lovely getting lectures from you
Axiom. "The total value of the resistors in parallel is less than the smallest"! Thanks for tutorial!
this really helped thank you so much
+shay campbell Great to hear, Shay!
It is clear, understandable, and short. That is the definition of AMAZING!
Since this is so easy, apply and demonstrate this method to the 3-dimensional cube, where every line represents a 1-ohm resistance.
8 junctions in all, and the power is connected diagonally
DEFINITELY going to make that video in the future - thanks, BelSei!
Can we use the current division and voltage division rules here ?
V=Vin ×Rsame branch/R total
I= I in × R opp branch/ R total
Really Masterpiece.Nobody in my school & private could teach me like you do.Thanks.I needed this. (I am now in 10th grade)
Legends say that this topic is made easy by you😁
why do i have the urge to applause?
why do i want to hug you? (i put immense effort into these videos and your kind words mean a lot to me)
its so simple, best for beginners. i am taking civil engineering but somehow have basic electrical engineering course and literally having hard time understanding this. thanks you saved me through semester.
This is a true breakdown
Yessir
Im gonna "breaket dawn naa" in class on monday
+masso172 LOL
+masso172 Hopefully you remembered to BUILDET UHP NAA!
Jesse Mason hahahah yes i did
Yes 👍👍

I have a physics final tomorrow and this method is so much faster that the way i used to do it. Thx man you rlly helpin people out
Day after tomorrow is my JEE exam and here I m watching it. 🔥🔥
Rank???
ah yes
is this even included in the silly bus
Thank You Jesse MAAAAAAAAAAAAASOON Love FROM India
Never thought I'd learn so much from a 5 year old video. I am doing electronics for my Diesel program and this helped me out so much. Thanks a ton!
how do you find the junction...? what if there is a juntiom where all resistor connect together?? how do we need to differentiate whether it is parallel or series??
The junction is where wires connect. They always mean that a parallel circuit is either starting or ending.
Jaymee Ong Bro, i am subscribed your channel and watch all the video and also like on the video. So please you are also subscribe my channel and watch the video,thanks for subscribe my channel
must say its done perfectly and effectively. loved it ..a lot..
Brother, this video is EXACTLY the video I needed. Thank you. Now I can get through my HW.
Ur teching goes well n super...
Thnq 4 ur wonderful video
You are amazing, you make physics super fun! Thank you for sharing your knowledge and expertise! God bless💜
That was such a nice comment - thanks so much, Gellie.
Still can’t understand why 1k persons to dislike that. Well done 💯
It's the dummy resistor step... that should have been a parenthetical comment... I took it too far. Sometimes I take things too far. Like this comment. I should've just thumbs-up'd your comment or said thank you... but I feel like I need to defend my teaching abilities from five years ago. So I make a long-winded reply no one will read deep in the comments section. Phew. Glad I got that out of my system.
well at 6:15, equivalent resistance is not 86 but 85.7ohm
Manjula MES 85,7~86, looks better and easy to work further
Could you tell me how did you work it out to come up with you answer?
if it is two resistances only a faster way to do it is to multiply them over their sum R1xR2/R1+R2
Actually it's 35ohms
