The instantaneous value of current in an A.C. circuit is `I=2sin(100pit+pi/3)A`. The current will be maximum for the first time at ……..

A

`t=1/100s`

B

`t=1/200s`

C

`t=1/400s`

D

`t=1/600`s

Text Solution

Verified by Experts

The correct Answer is:
D
`I=2sin(100pit+pi/3)`
If I=2A becomes equal to maximum value of current then,
`I=sin (100pit+pi/3)`
`therefore pi/2 = 100pit + pi/3`
`therefore 100t=1/2-1/3`
`therefore 100t=1/6`
`therefore t=1/600s`
