Q148 / 160 · AP EAMCET 2024 (19 May Shift 2) · Physics
A steady current is flowing in a metallic conductor of non-uniform cross section. The physical quantity which remains constant is
- AElectricity current density
- BDrift velocity
- CElectricity current density and drift velocity
- Correct answerDElectric current
Solution
For a metallic conductor of non-uniform cross section,
$\mathrm{I}_1=\mathrm{I}_2=\text { constant }$
Hence, the correct answer is option: 'D'.
