In a circuit, an inductor (L), capacitor (C) and resistor (R) are connected in parallel across a source of emf given by `epsilon=epsilon_(0) sin omega t`. Find the current through the mains and draw a phasor diagram.

A series LCR circuit consists of an inductor L a capacitor C and a resister R connected across a source of emf epsilon = epsilon_(0) sin omegat. When omegaL = (1)/(omegaC) the current in the circuit is l_(0) and if angular frequency of the source is changed to omega, the current in the circuit becoms (l_(0)/(2) then the value of |omega'L-(1)/(omega'C)| is
