An AC source of frequency

50\,\text{Hz}

is applied to a series combination of

R = 40\,\Omega

L = 0.20\,\text{H}

and

C = 100\,\mu\text{F}

. The approximate value of the phase angle

\phi

between the supply voltage and current is (a)

+67^{\circ}

(current lags) (b)

0^{\circ}

(c)

+38^{\circ}

(current lags) (d)

-38^{\circ}

(current leads)
