Hi everyone, I was wondering if anyone would be kind enough to help as to where to start with this homework question. It's due in two days and quite frankly I'm not sure where to begin.

A series R-L-C circuit comprises a 5μF capacitor, a 4Ω resistor and a variable inductance L. The supply voltage is 10 volts at a frequency of 159.1 Hz. The inductance is adjusted until the pd across the resistance is maximum. Determine for this condition the value of the inductance.

Thank you for any advice given.
