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:, Current, Drift velocity, Electric field, Current density

MARKS App · Accepted Answer

Current flow across the metallic conductor remains constant because the area of cross-section of conductor is non-uniform. So, Current density will be different but the number of flow of electrons will be same.
