A coil of inductance 318.3mH and negligible resistance is linked in series with a 200 resistor to a 240V, 50Hz supply.
Calculate
(a) The inductive reactance of the coil,
(b) The impedance of the circuit,
(c) The current in the circuit,
(d) The p.d. across each component, and
(e) The circuit phase angle.
