Quiz 10 -- ac Circuit

A coil of inductance 88 mH and unknown resistance and a 0.94 microF capacitor are connected in series with an alternating emf of frequency 930 Hz. If the phase angle between the applied voltage and current is 75 degrees, what is the resistance of the coil?

If the emf has magnitude 50 V, what is the current in the circuit?
