An alternating current is given by i(t) '=14.14 sin 377t' .
Hi there ,
Your question is incomplete. You didn't mention what is to find out. But I am assuming you have to calculate frequency.
So it is given that i(t)= 14.14 sjn 377t
now I= Im sinwt= Imsin2pieft
Given 2pief= 377
f= 377/2pie= 60 Hz
I have written pie instead of its symbol but you have to use symbol.
Hope it helps you
Good Luck!
