In the given figure, the input frequency is such that R = XC. Then

32-346

[A].	v0 lags vi by 45°
[B].	v0 lags vi by 90°
[C].	v0 leads vi by 45°
[D].	v0 leads vi by 90°

Answer: Option A

Explanation:

R = XC, voltage drops across R and XC are equal and at 90° with respect by each other. V0 lags Vi by 45°.
