The instantaneous current from an AC source is given by `I=5sin314t.` What is the rms value of the current ?

Text Solution

Verified by Experts

Given : `I=5sin314t" "…(1)`
We know that `I=I_(m)sinomegat" "...(2)`
Comparing (1)`&`(2)
`I_(m)=5A`
= 314
`I_(rms)=(I_(m))/(sqrt(2))=(5)/(sqrt(2))=3.536A`
