Voltage obtained in one A.C. generator `V=V_0 cos omegat` . If `V_0` = 10 volt and frequency v=50 Hz then voltage at time `t=1/600s` wiil be _____

A

10 V

B

5 V

C

`5sqrt3V`

D

1V

Text Solution

Verified by Experts

The correct Answer is:
C
We are given `V=V_0 cos (omegat)`
`therefore V=V_0 cos (2pivt) (because omega=2piv)`
`=10 cos (2pixx50xx1/600)`
`=10 cos (pi/6)`
`=10xxsqrt3/2`
`therefore V=5sqrt3` volt
