A steady current flow in a metallic conductor of non-uniform cross section. The quantity/quantities that remains/remain constant along the length of the conductor is/are
View answer and explanation
Correct option: D
Current only
Option D (Current only) is correct because in a series circuit (like a conductor), the current is constant throughout, regardless of changes in cross-sectional area.
