Problem

A series RLC circuit draws an rms current of

2\,\text{A}

from a

120\,\text{V}

(50 Hz) supply. The circuit elements have

R = 40\,\Omega

X_L = 60\,\Omega

and

X_C = 30\,\Omega

. Calculate the phase angle between the supply voltage and the circuit current, correct to the nearest degree.
