In an AC circuit `I=100sin 200pit`. The time required for the current to achieve its peak value of will be

A

`(1)/(100)s`

B

`(1)/(200)s`

C

`(1)/(300)s`

D

`(1)/(400)s`

Text Solution

Verified by Experts

The correct Answer is:
D
The current takes `(T)/(4)`s to reach the peak value. In the given question, `(2pi)/(T)=200pi implies T=(1)/(100)s`
`therefore`Time to reach the peak value=`(1)/(400)s`
