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 314 t ,
Compare it with `I = I_(0) sin omega t`
`I_(0) = 10` amp, `I_(eff) = (I_(0))/(sqrt2) = (10)/(sqrt2) = 7.07 A`
`omega = 314 = 3.14 xx 100 = 100 pi`
`v = (omega)/(2 pi) = (100 pi)/(2 pi) = 50 Hz`
