The steady current flows in a metallic conductor of non-uniform cross-section. The

\mathrm{quantity}\,\,\mathrm{/}\,\mathrm{quantities}

constant along the length of the conductor

\mathrm{is}\,\,\mathrm{/}\,\,\mathrm{are}

View answer and explanation

Correct option: D

Current only

Option D (Current only) is correct because in a non-uniform conductor with steady current, the current remains constant throughout the length, while the electric field and drift velocity vary due to the changing cross-sectional area.
