My mates and I are very grateful for all your videos sir. We appreciate you. My final is after tomorrow, and if I get a good mark, I truly owe some of it to you! Also, I became interested in Physics after understanding it with your simple and interesting explanations.

Resistance can vary in many materials, like gases, electrolytes, semiconductors and even in metals at high current densities. Ohm's law really only works for metals when the current isn't too high but it is nevertheless a very useful formula.

could you consider resistance to be the speed at which you are losing volts?

In the example isn't the diameter rhe cross section of the wire

The cross section refers to the cross-sectional area of the wire, which is usually but not always in the shape of a circle. It's a 2D area, not a line like a diameter

@@AndyMasley ok so I have to use πr^2 to find the cross sectional area. Thank you sir.
