Question

An AC voltage is applied to a circuit consisting of a resistor and inductor in series. If the resistance and inductive reactance of both are $3 \Omega$, what is the phase difference between the applied voltage and current in the circuit?

Phase difference $	an \phi = \frac{X_L}{R} = \frac{3}{3} = 1$, thus $\phi = \frac{\pi}{4}$.
