Vedclass · Answer

(A) The drift velocity $V_{d}$ of electrons in a conductor is given by the formula: $V_{d} = \frac{eE	au}{m}$.Since the electric field $E$ is related to the potential difference $V$ across a wire of length $L$ by $E = \frac{V}{L}$,we can substitute this into the equation:$V_{d} = \frac{e}{m} \left( \frac{V}{L} ight) 	au$.From this expression,it is clear that $V_{d} \propto V$.Therefore,if the potential difference $V$ is doubled,the drift velocity $V_{d}$ will also be doubled.

$A$ potential difference is applied across the ends of a metallic wire. If the potential difference is doubled,then the drift velocity
