Question: An alternating E.M.F. E sin pt is applied to a circuit at t=0. Given the equation for the current i asLd2idt2+Rdidt+iC=pEcospt, find the current i when (i)CR2>4L, (ii) CR2<4L.
An alternating E $.$ M $.$ F $. E$ sin $p t$ is applied to a circuit at $t = 0 .$ Given the equation for the current $i$ as
$L \frac{d^{2} i}{d t^{2}} + R \frac{d i}{d t} + \frac{i}{C} =$ pEcospt, find the current i when $(i) C R^{2} > 4 L,$
$($ ii $) C R^{2} < 4 L .$
