A sinusoidal voltage of peak value $\displaystyle 283$ V and angular frequency $\displaystyle 320$/s is applied to a series LCR circuit. Given that $\displaystyle \mathrm{R}=5 \Omega$, $\displaystyle \mathrm{L}=25 \mathrm{mH}$ and $\displaystyle \mathrm{C}=1000 \mu \mathrm{~F}$. The total impedance, and phase difference between the voltage across the source and the current will respectively be :
