List of top Physics Questions on Reactance

An alternating voltage V = $V_0 \sin \omega t$ is applied across a circuit. As result $I = I_0 \sin(\omega t - \pi /2)$ flows in it. The power consumed per cycle is

In an a.c. circuit with phase voltage V and current I, the power dissipated is

The reactance of an inductance of $0.01\, H$ to a $50 \,Hz$ A.C. is
