current electric field and drift velocity

B

drift speed only

C

current and drift speed

D

current only

Text Solution

Verified by Experts

The correct Answer is:
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
