Alternating Current

Question: An alternating current of frequency $f$ is flowing in a circuit containing a resistance $R$ and a choke $L$ in series. The impedance of this circuit is

1) $R + 2\pi fL$

2) $\sqrt {{R^2} + 4{\pi ^2}{f^2}{L^2}} $

3) $\sqrt {{R^2} + {L^2}} $

4) $\sqrt {{R^2} + 2\pi fL} $
