A virtual current of \( 4 A \) and \( 50 \mathrm{~Hz} \) flows in an ac
P circuit containing a coil. The power consumed in the

W coil is \( 240 \mathrm{~W} \). If the virtual voltage across the coil is \( 100 \mathrm{~V} \) its inductance will be
(1) \( \frac{1}{3 \pi} H \)
(2) \( \frac{1}{5 \pi} H \)
(3) \( \frac{1}{7 \pi} H \)
(4) \( \frac{1}{9 \pi} H \)
