Vedclass · Answer

(B) The induced $e.m.f.$ $(e)$ in an inductor is given by the formula: $|e| = L \frac{di}{dt}$ Given: Inductance $L = 10 \, \mu H = 10 	imes 10^{-6} \, H$ Change in current $di = 1 \, A - 0 \, A = 1 \, A$ Time interval $dt = 10 \, s$ Substituting the values into the formula: $|e| = (10 	imes 10^{-6} \, H) 	imes \frac{1 \, A}{10 \, s}$ $|e| = 10^{-6} \, V$ $|e| = 1 \, \mu V$ Therefore,the correct option is $B$.

Find out the $e.m.f.$ produced when the current changes from $0$ to $1 \, A$ in $10 \, s$,given $L = 10 \, \mu H$.
