Wire size vs Current

Learn how a wire's size in terms of thickness and length matters when handling large currents.

In this video we discuss how the resistance of a wire depends on its size and why this is important.

Good video, used it in my class. Just one thing though, electrons carry charge not current...current is just electrons flowing in a certain direction. If electrons are not moving they still carry charge and we refer to that as static electricity it becomes current when it flows. Good job though I like the quality of your video, short and precise.

U broke the argument I was having with my dad

Ok but what if you are powering something small 12v 2amps and use something like 10 awg wire

Everything is good, but it is true for Direct Current carrying. For AC, there is skin effect so the current carrying capacity increases with number of strands with the indiviual diameter remaining the same, thin.
