An $$R-L-C$$ circuit consists of a $$150 \Omega$$ resistor, $$20 \mu \mathrm{F}$$ capacitor and a 500 mH inductor connected in series with a 100 V AC supply. The angular frequency of the supply voltage is $$400 \mathrm{rad} \mathrm{s}^{-1}$$. The phase angle between current and the applied voltage is

$$\tan ^{-1}(0.8)$$

$$\tan ^{-1}(0.25)$$

$$\tan ^{-1}(0.6)$$

$$\tan ^{-1}(0.5)$$
