Automatic Control Systems
In the given figure, the input frequency is such that R = XC. Then
v0 lags vi by 45°
v0 lags vi by 90°
v0 leads vi by 45°
v0 leads vi by 90°
Correct Answer:
v0 lags vi by 45°
Explanation:
R = X
C
, voltage drops across R and X
C
are equal and at 90° with respect by each other. V
0
lags V
i
by 45°.
