Consider the circuit shown in the figure, In this circuit $\mathit{R}=1\mathit{k}\mathit{\Omega }$, and $\mathit{C}=1\mathit{\mu }\mathit{F}$. The input voltage is sinusoidal with a frequency of 50 Hz, represented as phasor with magnitude ${\mathit{V}}_{\mathit{i}}$ and phase angle 0 radian as shown in the figure. The output voltage is represented as a phasor with magnitude ${\mathit{V}}_0$ and phase angle $\mathit{\delta }$ radian. What is the value of output phase angle $\mathit{\delta }$ (in radian) relative to the phase angle of the input voltage?
