There is a reason why his videos are so effective. Ive noticed that his black background and light colours sometime create a photographic memory of the diagrams he draws. It helps understand all the concepts really good. I can imagine the motion in diagrams better in my mind.
I have never seen the teacher like you. I wish every teacher would be like you. If so all students would be brilliant and scholars. Words are very weak to express you. Because you are one of the person who made influence up on me to understand different subjects. Thanks A lot❤❤❤❤❤❤
May the Lord be with us all that are trying everything possible to pass our exam's otherwise this man came to make things easier thank you so much God keep you in good health 🙏
"By the way, you may want to take down these notes if you have a piece of paper" Chief I'm on video 3/5 of yours that I have open on my browser I've been taking notes each and every step of the way towards my exam tomorrow, you're the GOAT
Just the best of "BRILLIANT!!!!!" Nothing really new terms, yet clarified all most all the doubts. It's is worth your 1/2 an hour rather than a full day of "change in kinetic energy"😃.
Sir,I don't just know but since I encountered your video I have been doing well in my studies unlike before You are indeed God sent Am a student of UNIVERSITY OF NIGERIA NSUKKA and I just want to say a big thank you
I wasted so much time watching other videos trying to understand the difference between electric potential and electric potential energy. It put me almost a month behind in my Physics II class, and my test is tomorrow 😭 I found this video yesterday, and you did such an amazing job that I actually cried. I instantly got the membership and have been cramming ever since! I dont have much hope of passing this test with a great score, BUT I now have hope that I can catch up, and actually pass the class with an A or B. Thank you so much for all of the great content, and for giving me a fighting chance at passing my class!
Yeah same here I am a month behind as well. My prof doesn't really know how to lecture and uses the class time just for unnecessary stuff. My current grade rn in the class isn't looking good but I am still hanging on it and hoping to pass the class. :D Also, what's the update?
Okay so simple Electric potential( fuck wikipedia they're unreliable) is energy available to do work per unit of charge in an electric field. Voltage is the difference in electric potential between two points, basically the amount of work that was needed to move a unit of charge from its position at the first point to it's position at the second point in an electric field.
For question 3, because the charge first decelerates from B to A, then comes to a stop, then accelerates towards C, wouldn't the total work done on the charge be positive, the potential energy be decreasing and KE increasing? Wouldn't it just have less work done on it (in comparison to part a) because the work done moving from B to A is negative but the work done from A to C be positive and greater than the work from B to A?
4:43 this is backwards, isn't it? V_ab is the voltage at A with respect to B. You would write the integral with "a" as the lower limit and "b" as the upper limit. V_ab is Vb - Va. That makes me question a few things. Do people teach these terms differently?
hey comments, for question 3, the workdone can also be explained that w=-qv, and since -q is negative and v is due to the positive charge move from a to b where a has higher potential than b so that the potential differnce is also negative . making w positive right?
Wow, I havent seen a zig zag line as the circuit symbol for resistor since the 1970's, it brought back memories. The circuit symbol changed to a rectangle (in the UK) in the mid 70's!
I did charge transfer analysis on circuits junctions. I came to some theoretical conclusions: The electrons are transferred in pairs only. The number of electrons , on a closed dc circuit must be even. Static electron, entering a circuit, in his frame of refference sees both the - and the +. P.s My eduction is not formal, so i dont stick to conventions. Extrapulations mode suggest that there is something missing in the conventional way we treat charge. I cant put my finger on it , yet. The convention of + and - is incomplete/ over simplified.
In the Pearson textbook it is written that Vab = Vb -Va, which is the opposite of what's taught in this video, I wonder which is correct, or if there is a universally correct way?
Electric potential difference is defined as the difference between two points in an electric circuit carrying some current as the work done to move a unit charge from one point to another Does this make sense?
@TheOrganicChemistryTutor Does Phi mean Electric flux? Because Phi= E*A*Cos Theta (where theta is the angle between normal and electric field) Right? Thank you. P.S This question is based on the video of electric charges and fields.
please what is the difference between electric potential and electric potential energy? These terms are getting me confused 😕 by the way thanks for this you're a great teacher
@14:18 if the negative plate has a negative charge how can it have zero volts? Isnt zero volts associated with an object that has zero net charge? P.s. i watched this and other videos to get an understanding of what voltage is and how it works, and i still dont know. I saw electrons and protons emit an electric field and when two objects with equal opposite net charges are next to each other it creates a potential difference aka a voltage, but then you go and say a negatively charged plate has a voltage of zero. What makes it make even less sense is you are saying one plate with a net charge does have a voltage and the other plate that also has a net charge has no voltage. If an object with a net charge has a voltage, why does one plate have zero volts? Am i learning this wrong or is it being taught wrong?
How does a voltage develop across the unconnected end of a single wire connected to one terminal of a battery and the other terminal? If the battery’s net charge is zero, then for a 12 V battery, one terminal would be at a potential of +6 V with respect to a conductor at infinity, while the other terminal would be at -6 V. At the physical center in the space between the two terminals of the battery, the voltage is zero. If we then connect a small wire to, say, the positive terminal, a few excess point charges will move onto the wire, and that wire will now be at the same potential as the battery terminal: +6 V. The wire will be surrounded by an e-field, and since the lines of electrostatic flux must always terminate upon charges, the wires must possess an excess surface charge. In the above we assumed the net charge of the battery was zero. Supposing that the battery had a net charge. Then how would the charges, potentials and voltage be changed? Before we answer this, it would be instructive to understand Current, the conduction process and Voltage at the fundamental level. Electrostatics and circuits belong to one science not two as in the following two videos: i. ua-cam.com/video/REsWdd76qxc/v-deo.html and ii. ua-cam.com/video/8BQM_xw2Rfo/v-deo.html Returning to our question of the voltage of the single wire connected to one battery terminal, we assume the net charge of the battery was not initially zero. Perhaps someone with rubber-sole shoes carried the battery while walking on a wool carpet or perhaps the battery was charged to -5000 V, and would deliver a tiny spark if touched. In that case one terminal would still be 12 V different than the other terminal, perhaps -5000 V on the positive terminal and -5012 V on the negative. It is not possible in this brief post to discuss in more detail the process of production of the voltage of the single wire without a detailed discussion of the capacitance and potential of single conductors. The last frame References in video #1 lists textbook 4 which discusses these topics comprehensively using a unified approach and provides an intuitive understanding of voltage of a single short and long wire with and without a net charge on the battery.

No. This guy is fantastic. i finally understand this horror of electricity and electrical charge!!!!!
Very true
Somebody give this guy a raise, he’s helped out so much with physics..
i think this man was directly sent by God Himself
Come on bruh
whatvelse can it be
I think this man created god himself
Serious the man got a gift from heaven
@@alexchristensen9537 god cant be created, he has not beginning
I have never seen the teacher like you. I wish every teacher would be like you.
If so all students would be brilliant and scholars.
Words are very weak to express you. Because you are one of the person who made influence up on me to understand different subjects.
Thanks A lot❤❤❤❤❤❤
I didn’t think anyone could talk about electric potential for 33 mins. Good stuff!

Tysm for your videos :)
I don't know how to describe this man. I always refer to his video when I get something complex.You are really unique sir, thank you!!
Have you read my mind? I've started studying about electric potential 2 days ago and you uploaded this video.
same lol I think most first year eng students are covering electromagnetism right now
@@ghislainr5127 same thing happen to me..i just searched
I'm not trying to ruin your moment of anything, but he reuploads videos quite often, including this one.
I now completely understood the concept of potential energy. Wow! Thank you very much, JG.
Teaching way better information than the teachers we pay in school.
Julio Gonzales, you are the greatest of them all. Shaping engineers into the real world. Thank you so much son.
May the Lord be with us all that are trying everything possible to pass our exam's otherwise this man came to make things easier thank you so much God keep you in good health 🙏
This is so wholesome
Amen.
Ameen
Thank you for being my professor in Physics for my entire college life
Please please do not stop the good work you are doing,you don't know what you are doing to the world

It's just that I can't reach directly to JG I owe him my academic life .since high school now am at the University. Your my hero man.👍💖💖💖💖💖
I found electric physics complicated and complex,but with you existing,you saved my life.
I'm definitely learning all on electricity from This channel...with This channel I'm confident I'm gonna pass my phs 102 this semester
did you pass?
Oh my god. How can anyone be so perfect at teaching equally in math, physics, chemistry? this guy has my utmost lovreand respect
Why???? I just had my electrostatic test this morning 😭😭😭. I wish I could watch this video 1 day earlier.
God Bless you man. I was so bad at grasping all the charge, current, amp, culomb. Now I get it. I am watching ALL YOUR VIDEOS.
This man is amazing, he knows everything, may God bless you for saving us
I was watching while eating chips until minute (3:03) when I started taking notes. Thank you JG (((:
wow these videos are so helpful and make sense and are clear about everything you need to know
Just the best of "BRILLIANT!!!!!"

You are indeed God sent
Am a student of UNIVERSITY OF NIGERIA NSUKKA and I just want to say a big thank you
Honestly I would’ve been screwed without this man, the instructors in my school have all been trash. Calculus, Algebra, Chemistry, and Physics.
Hey . I'm here to thank you for being the BEST Awesome Teacher of this world
Ever video of this Chanel inspire me to fullfill my dream.
As I want to be a chemist
This is totally the best physics teacher you could ever have!!
Thankuu so much , i have exam this morning, and im studying electric potential just this morning ❤
For sure we are all STEM students here, hope we all achieve our dreams tho!! keep moving!
Thank you so much JG in a country where my teachers don't really teach us wel.l your videos are the absolute best thing that has happened to me😫😫😫❤️❤️
Everything you thought was all in my study materials word for word provided by my lecturer
This guy seems to have a video on every topic I have a doubt in
Test on Tuesday. This helps a lot!!!!
You Are The BEST!!!!!!💖💖💖
Please can you do videos about normality of salts and redox reactions 🙏🙏
Thanks fo all you do!

You're literally saving my life rn. my prof sucks lol
HOW THE FUCK IS THIS GUY THIS SMART, he could probably teach every subject in high school and do a better job than 99 percent of the other teachers.
Concise and brilliant delivery. Thumb up 👍

YOU ARE AWESOME JG TUTOR ! MILLIONS OF THANK YOU
this mans the goat no cap
this is the best
my exam is tomorrow and i was weak on this subject
this really helped me out
thank you
Your video are masterpieces . Thank you.
bro this man is saving my grades holy
You're the best ❤
You're the king of science! Thank you very much.
So good for sharing Physics knowledge. Thank you so much, sir.

Make W subject
Why do I pay tuition for college. 33 minute video and I learned more than I have in 2 hours of lectures.
Wish he talked more about the relation between electric potential and electric field
Wow, I havent seen a zig zag line as the circuit symbol for resistor since the 1970's, it brought back memories. The circuit symbol changed to a rectangle (in the UK) in the mid 70's!

thank you for making this, although it's similar to my note lecture, it's still refreshing to watched it and learned more.. ❤️
wallahi im finished i dont get it
Revisit the basics of E fields. That may help
Same
you are the best forever
You are a great teacher I am watched your some video you are great

Does this make sense?
This is a godsend. Hopefully I'll make it this quarter.
Broo!! I still convinced that u were sent by God. Thank you soo much man
Going through all this praying I can get through my Physics 11C class 🙏
I will be a senior soon , you helped me since year 8 in school! Thank you so much!🥹
what is the relationship between sign of the charge and the electric potential?
Man I think I should drop out of uni and just keep up with your videos to date.
I love this man he saved my life multiple times
Man God bless u

Thanks man for this work !
Someone explains to me please why sometimes the negative sign for the work formula is skipped, to me it does not make any sense to skip it.
Thank you a lot Mr if it were not you i don't know.
Love your videos
I can't thank you enough!
I mean we got people buying full length videos on the hub but why hesitate here
please because I can’t be the only one that hears mark walhberg

When we say from A to B or B to A do we mean the direction of the electrons or the direction of the current?
