Answer the following question. DC current flows in a metal piece of the non-uniform cross-section. Which of these quantities remains constant along the conductor: current, current density, or drift - Physics

DC current flows in a metal piece of the non-uniform cross-section. Which of these quantities remains constant along the conductor: current, current density, or drift speed?

Solution

Drift velocity and current density will change as it depends upon the area of cross-section whereas current will remain constant.

Concept: Drift Speed
Is there an error in this question or solution?
