An ideal inductor of $\left(\frac{1}{\pi}\right) H$ is connected in series with a $300 \Omega$ resistor. If a $20 \ V, 200 \ Hz$ alternating source is connected across the combination,the phase difference between the voltage and current is
- A$\tan^{-1}\left(\frac{3}{4}\right)$
- B$\tan^{-1}\left(\frac{4}{3}\right)$
- C$\tan^{-1}\left(\frac{5}{4}\right)$
- D$\tan^{-1}\left(\frac{4}{5}\right)$
