The size of the electric current in a electrical conductor is a function of which of the following?
A) velocity of charge carriers
B) conductor cross sectional area
C) density of charge carriers
D) All of the above choices are valid.

Question

Quizplus · Accepted Answer

The size of the electric current is determined by the number of charge carriers passing through the conductor per second, which is directly proportional to the density of charge carriers and the velocity at which they are moving. The conductor cross-sectional area also plays a role in determining the current, as a larger cross-sectional area allows for more charge carriers to flow through. Therefore, all of the given choices are valid and contribute to the size of the electric current in a conductor.
