The peak value of an alternating current...

The peak value of an alternating current is `5 A` and its frequency is `60 Hz`. Find its rms value. How long will the current take to reach the peak value starting from zero?

A

3.536 A, 4.167 ms

B

3.536 A, 15 ms

C

6.07 A, 10 ms

D

2.536 A, 4.167 ms

Text Solution

Verified by Experts

The correct Answer is:
A
`underset(rms)(I)` = `underset(o)(I)`/ `sqrt 2` = 5/`sqrt 2` = 3.536 A
Time taken, T = 1/`4 xx 60` = 4.167ms
