When a capacitor is in series with a resistance of 30 Ω, the current taken from a 240 V RMS, 50 Hz supply is 4.8 A RMS. What is (a) the impedance of the circuit, (b) the capacitance?

A voltage of 50 V RMS, 50 Hz is applied to a series RC circuit. If the current taken is 1.7 A when the voltage drop across the resistor is 34 V, what is the capacitance of the capacitor?
