If the frequency in an A.C. circuit is 100 Hz, then the time taken by the voltage to cover from maximum to next positive maximum will be

A

`5 xx 10^(-3) s`

B

`10 xx 10^(-3) s`

C

`20 xx 10^(-3) s`

D

`30 xx 10^(-3) s`

Text Solution

Verified by Experts

The correct Answer is:
B
`T = 1/n=1/100 s = 10^(-2)s`
`:.` Time to go from +ve maximum
`T = 10 xx 10^(-3) s = 10` millisecond.
