Question
Across a metallic conductor of non-uniform cross section a constant potential difference is applied. The quantity which remains constant along the conductor is :
Options
A.current
B.drift velocity
C.electric field
D.current density
Solution
Metallic conductor can be considered as the combination of various conductors connected in series combination. And in series combination the current always remains constant.

Hence option (1)

Hence option (1)
