A steady current flows in a metallic conductor of non-uniform cross-section. Which of these quantities is constant along the conductor?

A
Electric field
B
Drift velocity
Correct answer
C
Current
D
Current density

Solution

The current flowing through a conductor of non-uniform cross-section remain same in the whole of the conductor.

Hence, the correct answer is option: 'C'.
