An inductor “L” is connected in series with a Resistor “R”. This circuit is connected to
a sinusoidal voltage “V”, and a current of 1A flows. If the circuit resistor has a value
of 1W, and the magnitude of the reactance of the inductor “L” is 1W at the supply
frequency, state:

(i) The phase angle of the current with respect to the supply voltage

(ii) The magnitude of the voltage developed across the Resistor “R”, and the
inductor “L”



Like where do I even start? what equations should I be looking at?
