A coil of inductance 50 mH and resistance 15 Ω is connected across a 240 V RMS, 50 Hz supply. Determine the circuit impedance, the current taken and the phase angle between the current and voltage.

A coil has a resistance of 15 Ω and an inductive reactance of 8 Ω. Determine the impedance of the coil and the phase angle between the voltage across the coil and the current through it.
