Electrons drift with speed ${\mathrm{v}}_{\mathrm{d}}$ in a conductor with potential difference V across its ends. If V is reduced to $\left(\frac{\mathrm{V}}{2}\right)$, their drift speed will become :

Question

YESPYQ · Accepted Answer

Correct answer: a) $\frac{{\mathrm{v}}_{\mathrm{d}}}{2}$. The drift velocity ${v}_{d}$ is related to the potential difference V by the equation:${v}_{d}=\frac{eV\zeta }{ml}$. ${v}_{d}\alpha V$ Thus, when the potential difference is halved, the drift velocity will also be halved
