You have definitely helped in the last hour you have show me to to do series parallel and combination and I've been struggling with learning them for the week leading up to my test
You my good sir in the 12 minutes of explaining the different types of circuit boards and how to solve for them have helped me learn more in 12 minutes than my teacher has done in 3 weeks. thank you!
wow, literally saved me from having a breakdown. This was really easy to understand, thank you for putting the time and effort (if needed) into making this!
Omg you explained so well!!!! I just watched your series and parallel circuit video and it helped so much 😭😭thank you so much! Lol I know it was 5years ago but you should know that you’re still helping people today
Super good video! This helped a lot with understanding combination circuits! The drawings were a bit messy which made it slightly harder to understand, but with some extra visualization it was fine. Nicely explained and nice numbers you worked with. Thanks!
Thank you for making this video. This video is perfect for those who are already familiar with ohms law. I used this video to help me work out a combination circuit. It was a great help.
Thank you so much, you don't understand how helpful this was! I really wish you were my teacher, you're so good at explaining things. I was having a lot of trouble with this until I stumbled across your 3 videos where you solved for series, then parallel, and now combination! Keep up the great work sir :D
THIS MAKES SO MUCH SENSE! I am trying to get into the Cathodic Protection field. The NACE Instructors are so far advanced it's like rocket science. This is great, THANK YOU!
Takes practice to get these down. I tried to master combination circuits in one day and it didn't work out. After doing a few different circuits it becomes easier.
in every video I see for these kinds of circuit math problems, the resistor values are already given. I would love to see a video where you only have 1 resistor value given and have to solve for the rest before you can start merging resistor branches.
you're a saviour really, my teacher never teach us anything since pandemic and our modules lacks in lessons, lol, she should be fired, kidding HAAHAHAH I love youuu you saved meeeeeeeee 😭😭😭😭
Question if R1 and R2 in the first example on the left are in series and R2 and R3 are in parallel does it mean to say that R1 and R3 relationship is series or that is a wrong conclusion to say?
Question...in the 2nd example to the right after you condensed it down to 2 parallel resistors why can u not simplify/condense it further and add resistors r1/r2. And r3/r4 together into 1 series resistor/circuit making it even more simple yet!? Sorry I'm totally new to this! Thx for any and all info!
Quick question...so is it still wrong if I get approximate answers when doing the computations? For example, you got 2.6V, but I got 2.74V....and do we round off to the nearest tenth or the mearest hundredth?
I'm not super particular about it, but technically we should be following the rules of significant figures to know how many numbers we should be rounding to.
Working through a combo worksheet for an electrical course right now and after watching this plus my instructors lessons, I still don't get it.. I think I'm hopeless lol. Maybe one day things will click, but today is not that day.
Thank you so much, I have watched your How to solve a series, parallel and combination circuit videos, they have helped me out a lot and were easy to understand, Keep up the great work!
derick palmer because you have to solve for the reciprocal meaning you have to flip the the numbers. So instead of solving for 2/5 which would be 0.4 what you initially thought the answer was, you’re actually suppose to solve for 5/2 and your answer would be 2.5.
I don't get it defies math for a bit In the first example R2 is like in a different side against R3 but both of them are parallel at each other. But why is the second example R12 and R34 instead of R13 and R24?
In the math problem I solved, if we were to take out R1 then the whole circuit would break. If you took out one of the parallel ones, nothing would burn out.
It does but to calculate it in negative would be really annoying. So conventional theory just stays positive for the sake of less negative numbers. If you are involved with engineering then you might calculate from negative to positive.
The equation for total resistance in parallel is 1/Rt. Since we want Rt and not 1/Rt we either have to flip the fraction or cross multiply. I chose to flip the fraction. Both methods will get you the same answer.
Does anyone know how to solve a parallel circuit if a resistor is unknown in a branch? I have in total 5 resistors. - 2 in one branch (with 1 unknown) -1 -2 in one branch
I think he doesnt know about the cross multiply rule you're referring too. Like St=R1×R2÷R1+R2 You got a different number because he also did his equation wrong; its suppose to be 1/Rtotal= 1/r +1/r+1/r
Got the message, but it is hard work following your 'shooting cursor' around the board. And you need to enlarge the images at source. The figures and symbols are really sitting cheek by cheek. And your writing leaves a lot to be desired. Otherwise, an excellent presentation.
Please help i dont understand. Help me solve this. In a combined circuit where there is 220V, R1=11 is in a parallel and the outermost have 2 parallels which r2=15 and r3=19. I tried your method but still I dont know how to do it. Please help anybody
You actually got that wrong. In getting I4 , 6.66V / 5R is actually 1.332A Which means V2 is 2R x 1.332A = 2.664V And V3 is 3R x 1.332A = 3.996V So V2 + V3 = 6.66 = V4 A1 or 2.66A is an exception to this because its 2 and .6 to infinity.
Oh and if you use 1.3A in V4 , It's actual sum is 6.5V. same as the sum V2 and V3 if you used 1.3A since V2 will become 2.6V and V3 is 3.9V adding up to 6.5V. Every little difference counts in math :)
You have explained this better in 12 minutes than my professor did in three weeks
YES!
You got 3 weeks to learn this? We are getting one week and getting tested 🫠
You have definitely helped in the last hour you have show me to to do series parallel and combination and I've been struggling with learning them for the week leading up to my test

WHAT IM SAYING
As an electrical apprentice digging up your video. Saved me countless headaches trying to solve these.
Thank you so much. I don’t understand how my teacher explains things. You just saved me. I love you
You my good sir in the 12 minutes of explaining the different types of circuit boards and how to solve for them have helped me learn more in 12 minutes than my teacher has done in 3 weeks. thank you!
wow, literally saved me from having a breakdown. This was really easy to understand, thank you for putting the time and effort (if needed) into making this!
sameeeeee Jesús crist
Same for me, almost failed a test becuz I didn’t know this
I know this is an old video but your playlist solving series/parallel/combination circuits literally saved my grade, thank you so much!
Just started an electrical tech degree. You sir solved a lot of late night headscratching. Thank you for that video
how are hings going in your degree bro?
I have a test today in Italian but I speak English, so I don't understand anything my teachers say, thanks for explaining so well
Omg it finally makes sense. I've heard many people explain it but the tables and math explained it perfectly. I will watch this over and over .
Omg you explained so well!!!! I just watched your series and parallel circuit video and it helped so much 😭😭thank you so much! Lol I know it was 5years ago but you should know that you’re still helping people today
will thx...you just made my professor look like idiot
hahahaha same here
its 7:18 a.m this is the final video I can watch before exam and it has done a great job making me understand thank you so much
Super helpful, after not learning these since I was in school, you've managed to bring all my memory's back and nail this. THANKYOU
Super good video! This helped a lot with understanding combination circuits! The drawings were a bit messy which made it slightly harder to understand, but with some extra visualization it was fine. Nicely explained and nice numbers you worked with. Thanks!
You just saved me from my finals. Words can not describe how much I love u
very helpful and not as complicated as all the other tutorials that the internet presents
Thank you so much, I couldn't find a good explanation for this ANYWHERE!! This was so helpful.
Thanks for sharing this walkthrough on combination circuits, was scratching my head trying to visualize this in my code book.
Thank you for making this video. This video is perfect for those who are already familiar with ohms law. I used this video to help me work out a combination circuit. It was a great help.
Thank you so much, you don't understand how helpful this was! I really wish you were my teacher, you're so good at explaining things.

straight to the point thanks man really needed that help !!
THIS MAKES SO MUCH SENSE! I am trying to get into the Cathodic Protection field. The NACE Instructors are so far advanced it's like rocket science. This is great, THANK YOU!
Good luck!
Very Clear...Great teaching Methods.
Takes practice to get these down. I tried to master combination circuits in one day and it didn't work out. After doing a few different circuits it becomes easier.
this is the best explanation i have seen on youtube so far, thank you!!!
Nobody ever explains how to get the voltage drop on resistors that are in series but part of a larger parallel circuit. Golden.
thx you for this video, i learned this in my class but totaly forgot it, thx for making it short and understandeble! :) much love.
Why 2.67- 1.3 is equal to 1.3 instead of 1.37?
Sorry if I was too late to reply, but it is a basic law that you have to cut down significant figures depending on how much there is to put.
With solving for RT, why did you use the reciprocal? Specifically, when do you know to flip the equation? 2/5 to 5/2?
You explained this amazingly! Thank you so much, this helped me understand this topic much more easily for my Electrical Technician program. :)
in every video I see for these kinds of circuit math problems, the resistor values are already given. I would love to see a video where you only have 1 resistor value given and have to solve for the rest before you can start merging resistor branches.
Imma ace my test on Friday, Thank you so so so so much,❤️🙏
Thanks for the video. My College Professor doesn't explain things easy at all. This saved me from staying at a C+ average.
you're a saviour really, my teacher never teach us anything since pandemic and our modules lacks in lessons, lol, she should be fired, kidding HAAHAHAH
I love youuu you saved meeeeeeeee 😭😭😭😭
Question if R1 and R2 in the first example on the left are in series and R2 and R3 are in parallel does it mean to say that R1 and R3 relationship is series or that is a wrong conclusion to say?
How did you get 2.67A for current of resistor 1? Would have been a bit more helpful if you explained that, or the formula?
Your better than my professor i learned so much in 12 mins vs 2 weeks lol
Question...in the 2nd example to the right after you condensed it down to 2 parallel resistors why can u not simplify/condense it further and add resistors r1/r2. And r3/r4 together into 1 series resistor/circuit making it even more simple yet!? Sorry I'm totally new to this! Thx for any and all info!
You flippin legend mate
you just made my night , thank you
Wow what an easy way you taught ?
Really amazing.
Impressive, I wish I would have seen this before my exam.
YOURE A CHAD THANK YOU
Quick question...so is it still wrong if I get approximate answers when doing the computations? For example, you got 2.6V, but I got 2.74V....and do we round off to the nearest tenth or the mearest hundredth?
I'm not super particular about it, but technically we should be following the rules of significant figures to know how many numbers we should be rounding to.
Thank god I finally understand 8:27 I was so confused on how the current changes
What if I dont have a resistor in the R1 position, how do I do it then?
Sorry I should've listened first thankyou for teaching me.
Thanks your for teaching for me
you taught me more in 12 mins then my prof did in a week
hi i was just wondering, is this the same as a complex circuit?
really really apreciate you blessinngs
So well explained, thx
Why did you flip from 2/5 to 5/2 was that a magic or a normal rule
It's a rule in solving for total resistance in parallel.
Mad helpful!
Thank you for this video, it absolutely helped!
Working through a combo worksheet for an electrical course right now and after watching this plus my instructors lessons, I still don't get it.. I think I'm hopeless lol. Maybe one day things will click, but today is not that day.
R1, R2 and R3 are in series, so why weren’t they just added up in the beginning? Making R 1,2,3 = 7ohms
That doesnt make sense.
Liban
Yeah, I figured it out shortly after making that comment.
What do you do if you have no R1
Ang galing
Thank you so much, I have watched your How to solve a series, parallel and combination circuit videos, they have helped me out a lot and were easy to understand, Keep up the great work!
Brilliant!
Thanks! But is I1 correct? I think it is 6A.
this video is god tier
Why is the result of the parallel portion 2.5 instead of 0.4?
derick palmer because you have to solve for the reciprocal meaning you have to flip the the numbers. So instead of solving for 2/5 which would be 0.4 what you initially thought the answer was, you’re actually suppose to solve for 5/2 and your answer would be 2.5.
I don't get it defies math for a bit
In the first example R2 is like in a different side against R3 but both of them are parallel at each other.
But why is the second example R12 and R34 instead of R13 and R24?
If I take out the series bulb, will the parallel bulbs burn out?
And if I take a parallel bulb, will the series bulb burn out? Please answerr
In the math problem I solved, if we were to take out R1 then the whole circuit would break. If you took out one of the parallel ones, nothing would burn out.
Thank you so much!
What is this program called would love to use it ? Way better than my teacher lol!!!!
SwordSoft Ink Free.
why didnt you just add R1+R2+R3 in a series, then do a parallel to R4? Would that work?
gabriel espinosa Since R1 is not in series with R2 and R3 you cannot do that.
why was the 2/5 flipped and made 5/2 for the R234 total?
That's the rule when finding total resistance in a parallel circuit.
Looks like I should've written the equation for that as 1/Rt = 1/R23 + 1/R4
@7:05 doesn’t current flow from negative to positive?
It does but you can calculate it either way, just as long as you stay consistent.
It depends on the theory. Conventional theory States positive to negative, electron flow theory states negative to positive
It does but to calculate it in negative would be really annoying. So conventional theory just stays positive for the sake of less negative numbers. If you are involved with engineering then you might calculate from negative to positive.
Thank you my stupid online courses do a horrible job at explaining this stuff.
im a dumb guy when it comes to any math subject, i just wanna ask why did you flip the 2/5 in 5:21
The equation for total resistance in parallel is 1/Rt. Since we want Rt and not 1/Rt we either have to flip the fraction or cross multiply. I chose to flip the fraction. Both methods will get you the same answer.
how does it become 1.3 amps?
What if there’s no total voltage and resistance?
thanks brotha
Btw I thought we have to use the formula the parallel circuits R2 and R3 to get their total ohms by this
formula: RT=1/R1+1/R2+1R3.....1/Rn
You like bill nie the science guy had a baby with Google thanks for all the vidos
Your amazing!
How do you find the power as well???
P=IV
voltage should be 3.33 for R4, and like 1.67 for R2 & R3
Then how to check their total voltage current and resistor?
When you sum them up it is over to their total Voltage/Current/Resistor
Because it is a combination circuit you can't just sum them up, you would have to use rules for series and parallel at the appropriate time.
who else is here because the class this year is garbage
Me
Does anyone know how to solve a parallel circuit if a resistor is unknown in a branch? I have in total 5 resistors.
-
2 in one branch (with 1 unknown)
-1
-2 in one branch
why didn't you use the 'parallel rule' and instead simply did reciprocals? Parallel rule results in a different answer.. Please help - thank you!
Because this circuit has a combination of series and parallel, you have to use both series and parallel rules instead of just using parallel rules.
I think he doesnt know about the cross multiply rule you're referring too. Like St=R1×R2÷R1+R2
You got a different number because he also did his equation wrong; its suppose to be
1/Rtotal= 1/r +1/r+1/r
Just trying to understand bear with me.
Why the reciprocal from 2/5 to 5/2
That's the rule when adding resistors in parallel. Go watch my video on how to solve a parallel circuit.
Thank you soooooo much
Nice
Got the message, but it is hard work following your 'shooting cursor' around the board. And you need to enlarge the images at source. The figures and symbols are really sitting cheek by cheek. And your writing leaves a lot to be desired. Otherwise, an excellent presentation.
Its called Product over Sum. R2 x R3/ R2+R3 = R2,3
I need inductive and capacitive reactance
Please help i dont understand. Help me solve this. In a combined circuit where there is 220V, R1=11 is in a parallel and the outermost have 2 parallels which r2=15 and r3=19. I tried your method but still I dont know how to do it. Please help anybody
What are you trying to solve in this problem?
amaazing!
Wouldnt the R(t)= .40 because 2 divided by 5 is .40?
It was 1/5+1/5=2/5, yes, but you use the reciprocal in that method, which is 5/2=2.5
the amps for v3-4 is 1.37
why r1 and r2 not next to each other??? I'm confused.
Resistors don't need to be next to each other. Labeling them R1 and R2 is just a means to give them a name.
@@DMaciaga Ok thanks. Where does the current first enter? in r1 or in r2? I'm confused with the flow of the current.
Thanks for the response sir.
@@chlowiemarielacaba7080 I explain at 7:00 in the video.
nice dude
You actually got that wrong.
In getting I4 , 6.66V / 5R is actually 1.332A
Which means V2 is 2R x 1.332A = 2.664V
And V3 is 3R x 1.332A = 3.996V
So V2 + V3 = 6.66 = V4
A1 or 2.66A is an exception to this because its 2 and .6 to infinity.
Oh and if you use 1.3A in V4 , It's actual sum is 6.5V. same as the sum V2 and V3 if you used 1.3A since V2 will become 2.6V and V3 is 3.9V adding up to 6.5V.
Every little difference counts in math :)
Where is the 5.34 came from?
V=R¹×I¹
?=2 ohm's multiply 2.67 amps
= 5.34v
combination has the same current flow through all resistors. shouldnt it be IT=I1=I2=I3
Series uses that rule, parallel is IT=I1+I2+I3, etc, combination means the circuit uses series and parallel in combination
nice teach :-)
