Question

The instantaneous current from A.C source is I = 55 sin314t. What is peak value of current?

Answer 1

The maximum value of an alternating current is termed as peak value of an AC.

From sinusoidal Ac equation :

I=Io sinωt

now compare it with given equation:

I = 55 sin314t

Io=peak value= 55A

ω=314

so peak value of current will 55 A
