Consider the circuit shown in the figure, In this circuit \(R = 1k\Omega\), and \(C = 1\mu F\). The input voltage is sinusoidal with a frequency of 50 Hz, represented as phasor with magnitude \({V_i}\) and phase angle 0 radian as shown in the figure. The output voltage is represented as a phasor with magnitude \({V_0}\) and phase angle \(\delta\) radian. What is the value of output phase angle \(\delta\) (in radian) relative to the phase angle of the input voltage?

• A. 0
• B. \(\pi\)
• C. \(\frac{\pi }{2}\)
• D. \(- \frac{\pi }{2}\)
