For a series

RLC

circuit supplied at

50\,\text{Hz}

, the component values are

R = 60\,\Omega

L = 0.25\,\text{H}

and

C = 25\,\mu\text{F}

. Calculate (i) the phase angle between the supply voltage and the current, stating whether the current leads or lags, and (ii) the power factor of the circuit (correct to two decimal places).
