Question
A steady current is passing through a linear conductor of non uniform cross-section. The net quantity of charge crossing any cross section per second is:

Answer

  1. Independent of area of cross-section.
Explanation:
The quantity of charge passing through any cross-section per second is nothing but current flowing in the conductor.
As given, the current is steady current, means current is uniform throughout the cross-section. Hence it is independent of Area of cross section.
