An ac generator generates an emf .e. given by: `e=311sin(100pit)` volt. Find the rms value of the emf generated by the generator.

A

21.99 V

B

2.199 V

C

219.9 V

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
C
219.9 V
Explanation: `e=311sin(110pit)`
By `e=e_0sin(100pit)`
`e_0=311" volt"`
`e_"rms"=e_0/sqrt2=(311)/sqrt2`
`=219.9" volt"`
