Across a metallic conductor of non-uniform cross section

Home » Electricity and Magnetism » Current Electricity » 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 :

1. current
2. drift velocity
3. electric field
4. current density

Correct Option: A

Here, metallic conductor can be considered as the combination of various conductors connected in series. And in series combination current remains same.
