A) current leads the voltage by \[45{}^\circ \]
B) voltage leads the current by \[90{}^\circ \]
C) current leads the voltage by \[90{}^\circ \]
D) voltage leads the current by \[45{}^\circ \]
Correct Answer: C
Solution :
The phase difference between instantaneous values of I and Vis\[+\frac{\pi }{4}-\left( -\frac{\pi }{4} \right)=\frac{\pi }{2}\] Hence, current leads the voltage by\[90{}^\circ \].
