A coil has resistance 30 ohm and inductive reactance 20 ohm at \( 50 \mathrm{~Hz} \) frequency. If an \( \mathrm{AC} \) source, of 200 volt, \( 100 \mathrm{~Hz} \), is connected across the coil, the current in the coil will be:
a. \( 4.0 \mathrm{~A} \)
b. \( 8.0 \mathrm{~A} \)
c. \( \frac{20}{\sqrt{13}} \mathrm{~A} \)
d. \( 2.0 \mathrm{~A} \)
