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