Networks Analysis and Synthesis
35.
A current is flowing through a conductor with non-uniform area of cross-section. Then
current will be different at different cross-sections.
current will be the same at all the cross-sections.
current will be different but current density will be same at all the cross-sections
current will be the same but current density will be different at different cross-sections.
Answer: Option
Explanation:

Current density = current/area of cross-section. Same current throughout the conductor.

Since, area of cross-section is non-uniform, current density will be different at different cross-sections.
