Gauss's Law Example # 2

Is this why we say that charge is on the outside of wires?
Is this why we also say that the surface area of a large wire has more surface area and hence less resistance?
I feel like I am learning something, but not quite sure how it all comes together yet.
The sad part is; this has never made any sense to me; until was over 60 years old.
I wish I would have discovered this teacher when I was a young student.
I am as dumb as a stick, and yet I actually know what this guy is teaching.
No teacher has ever done that before. His speed, his repeating, his tone all works together.
If I was to take a guess, I would say that it takes a good understanding in order to
make it this simple. I am not saying that my teachers were lacking a good understanding,
I am saying that they didn't bother to teach in such a way to make the information simple.
Well done, I have given all your videos a thumbs up.

You sir, explained a concept that baffled my whole biomedicine class for two weeks, in less than 10 minutes. Bravo!

the best youtube lecture i ve ever seen

Awesome videos man. Fully explained and very detailed. Helped a lot.

If had this kind of lecture in zambia I think we have move far thanks lot I know like cant even explain how u have impact me

for gaussian surface inside the hollow sphere. If you consider the charge on sphere at the center instead of along the outer surface, the electric field would not go to zero isn't it?

You said E and dA had 90° angle between them. Why is it 0° with the Gaussian surface?
