A Coil of $0.01$ Henry inductance and 1 ohm resistance is connected to $200 \;volt,50 Hz,ac$ supply . Find the impedance of the circuit and time lag between max. alternating voltage and current .

Question

$\begin{array}{1 1} z= 3.30\;ohm , \Delta t= \large\frac{1}{250} \;sec \\ z= 330\;ohm , \Delta t= 250 \;sec \\ z= 0.330\;ohm , \Delta t= \large\frac{1}{250} \;sec \\ z= 3.30\;ohm , \Delta t= 250 \;sec \end{array}$
