The phase difference between current and...

The phase difference between current and voltage in an AC circuit is `(pi)/(4)` radian, If the frequency of AC is 50 Hz, then the phase difference is equivalent to the time difference:-

A

0.78s

B

15.7s

C

0.25s

D

2.5s

Text Solution

Verified by Experts

The correct Answer is:
D
`(Delta phi)/(2pi)=(Deltat)/T`
`:.Deltat=(Deltaphi)/(f(2pi))=(pi//4)/(50(2pi))`
`=1/100=2.5ms`
