Electric current consists of moving charges, usually electrons, which have a suprisingly low speed. The video explains the ideas and shows a sample calculati.

How fast do electrons move in electrical circuits? Here I show you how to derive the I = nAev equation you can use to work out the mean drift velocity of ele.

Unit 8 : Part 1 Electric Current and Resistance. Outline Batteries and Direct Current Current and Drift Velocity Resistance and Ohm’s Law Electric Power.

For many conductors of electricity, the electric current which will flow through them is directly proportional to the voltage applied to them. When a microscopic view of Ohm's law is taken, it is found to depend upon the fact that the drift velocity of charges through the material is proportional to the electric field in the conductor. The ratio of voltage to current is called the resistance, and if the ratio is constant over a wide range of voltages, the material is said to be an "ohmic"…
