The steady state output of the circuit shown in the figure is given by
$$$y\left( t \right) = {\rm A}\left( \omega \right)\sin \left( {\omega t + \phi \left( \omega \right)} \right)$$$
If the amplitude $$\left| {{\rm A}\left( \omega \right)} \right| = 0.25$$, then the frequency $$\omega $$ is

A series LCR circuit is operated at a frequency different from its resonant frequency. The
operating frequency is such that the current leads the supply voltage. The magnitude of
current is half the value at resonance. If the values of L, C and R are 1 H, 1 F and 1Ω ,
respectively, the operating angular frequency (in rad/s) is ________.
