In a purely resistive $ac$ circuit,the current

$A$ sinusoidal voltage $V(t) = 100 \sin(500t)$ is applied across a pure inductance of $L = 0.02 \, H$. The current through the coil is:

For high frequency,a capacitor offers

In a circuit,the current lags behind the voltage by a phase difference of $\pi / 2$. The circuit will contain which of the following?

In the graphical representation of e.m.f. $e$ and current $i$ versus $\omega t$ for an a.c. circuit,both emf and current reach zero,minimum,and maximum values at the same time. The circuit element connected to the source will be

In a purely inductive circuit,the current is
