Question

A Steady current flows in a metallic conductor of non uniform cross section. The quantity/quantities which remain constant along the length of the conductor is/are
A. current electric field and drift velocity
B. drift speed only
C. current and drift speed
D. current only

Answer 1

Correct Answer - d
Only currect through the conductor of non-uniform area of cross -section is constant .Drift velocity or drift speed vary inversely with the area of cross section of the conductor
