Vedclass · Answer

(C) When a potential difference $V$ is applied across a metallic conductor,an electric field $E$ is established inside the conductor directed from the higher potential end to the lower potential end.Since electrons are negatively charged,they experience an electric force $F = -eE$ in the direction opposite to the electric field.Therefore,the free electrons experience a force directed from the lower potential end to the higher potential end.Due to frequent collisions with the lattice ions,the electrons do not accelerate indefinitely but instead acquire a constant average velocity known as the drift velocity $(v_d)$ in the direction of the force (i.e.,from lower potential to higher potential).

When a potential difference is applied across a linear metallic conductor,then:
