The size of the electric current in an 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 in an electrical conductor is determined by the movement of electric charges or charge carriers. Therefore, the velocity of charge carriers plays a significant role in determining the size of the current. The current also depends on the conductor cross-sectional area since a larger area offers more space for the movement of charges. Similarly, the density of charge carriers is also vital in determining the current size. Hence, all of the above choices are valid and have an impact on the size of the electric current.
