What Is Electric Potential Difference?

This video explains what is electric potential difference. It also explains how to determine the direction of electric current flow in a resistor using the electric potential values across a resistor. It also explains how to determine the amount of current flowing in a resistor using voltage and ohm's law.

God bless your soul, you taught me more than 3 months of school (:

[desireekenaope]

having a test tomorrow this really helped...i also needed a video on relation between electric potential and electric field

[Mrtoasted]

TYSM For making this so easy, you just summarized 2 pages of words into a 5 min video

[IamKudos]

Hey man i needed help, can you upload a video on how to find the potential between the two points in a little more complicated circuits where there are series and parallel connections? Thanks for this one!

[lonescowt]

This man gonna help me increase my marks to pass physics. Really appreciate all the vids bro

[thex]

Thank you so much, you don’t understand how grateful I am sir

[akhilpokemon]

Can someone tell me what potential difference is exactly

[HanselLife]

The way yo presnt your opinion is absoluyely amazing Bacuse i liked it

[jkjokerlol]

So to clear one thing up, it's important to find the Direction of the current so that when writing the Potential Difference you know to put the greater valued voltage first and the lesser value voltage seconded? I did the second question on my own and had the numbers flipped so I got the wrong answer lol.
That aside, thank you. This video was very informative for a beginner!

Good lessons 👌🌺🌺👨‍🏫👩‍🏫 I have perfectly understood

[tomcruise]

But electron flow from high voltage to low voltage as high voltage will repel ...so current is opposite the flow of electrin so current direction must be from low voltage to high...explaun

[bunsovannra]

Hello teacher. can you tell me what
The program that you use to write it?

[ismaelsiwi]

thanks for the vid, it was very helpful indeed.

[ricebeans]

thank you so much i under stand it now hopefully i pass my exams

[JokeriHici]

What program are you using for explaining? What board is it?

[nicatrench]

sir what if the voltage is equal? is it the same process too??

[johnreymaliao]

What happen if there's a fault or ground fault in point A. what is the effect on a circuit and current flow..

[madhu-vvui]

oh my god thanks excellent .why is the voltage negative

[PeenTip]

Just remember this is how we read schematics but in reality the high potential(+) has less electrons than low potential (-) more electrons. Electrons want to go to the high potential to fill in those holes in the valence shell. So a battery provides the energy needed to move the electrons from point a to point b

[ayseuzan]

The current flows from B to A. Shouldn't the difference be A-B?
So, -30-(-12)=-18V even though the answers are the same.
