1. To an AC power supply of $220\text{ V}$ at $50\text{ Hz}$, a resistor of $20\,\Omega$, a capacitor of reactance $25\,\Omega$ and an inductor of reactance $45\,\Omega$ are connected in series. The corresponding current in the circuit and the phase angle between the current and the voltage is, respectively:
