For an alternating voltave V=10 cos 100 ...

For an alternating voltave `V=10 cos 100 pit` volt, the instantenous voltage at `t=1/600`s is

A

`1V`

B

`5V`

C

`5sqrt(3)V`

D

`10V`

Text Solution

Verified by Experts

The correct Answer is:
C
Substituting `t=1/600 s` in the given equaltion, we have
`V=10cos(100pi)(1/600)`
`=10cos.(pi)/(6)`
`=5sqrt(3) V`
