The instantananeous current from an a.c. is `I = 10 sin 314 t`. What is the frequency of the source and virtual value of current ?

Text Solution

Verified by Experts

Here, `I = 10 sin 314t`
Compare with standard from :
`I = I_(0) sin 2 pi v t`
`I_(0) = 10 A, 2 pi v = 314 , v = (314)/(2 xx 3.14) = 50 Hz`
`I_(v) = (I_(0))/(sqrt 2) = (10)/(1.414) = 7.07 A`
