College Physics 2: Lecture 9 - Calculating Electric Potential

In this lecture, we analyze how to calculate the electric potential both at a point between the plates of a parallel plate capacitor and at a point in space around a point charge.

Your channel is the best. I am currently not studying for some reasons, but I use your lectures to study on my own. Thank you very much for this, your explanations are excellent. I hope you keep this channel alive, again thank you!!!

Hi Mr. Spahn, could you please upload lectures 10 through 16, thanks

Sir, could you upload lectures 10 through 16 for physics 2.

Thanks for sharing this content! At around 41:20, for #4, wouldn't the electric potential energy increase from point 'i' to point 'f'? At point 'i', both positives should be canceling each other out, leaving the electric potential energy at 0. At point 'f', if we do a vectors sum, the two positives should be pushing our positive test charge straight up, meaning it'll have some electric potential energy. So I think point 'f' would have a higher electric potential energy than point 'i'. Correct me if I'm reading it wrong!

When are you going upload your next video?

Your lectures is so helpful. I need a math learning videos like this.
Where I can find it?

Is electric potential energy also a scalar like electric potential?

will you continue posting your lectures throughout the semester? they are very helpful
