The average current of full cycle of a.c is, if peak current is i_(0)

Find the peak value and mean value of current over a half cycle if effective current in 40 Hz AC circuit is 7 A .

In an AC circuit of 100 Hz, the effective value of current is 6 A. Calculate (i) the peak value of current (ii) mean value of current over half cycle and (iii) value of current 1/ 500 s after it was zero .

The rms value of current in an ac circuit is 25 A, then peak current is

The average emf during the positive half cycle of an ac supply of peak value E_(0) is .

In A.C. circuit the average value per cycle of e.m.f. or current is -

If the effective value of current in 50 Hz a.c. circuit is 5.0 A, What is (i) peak value or current (ii) mean value of current over half a cycle (iii) value of current 1//300 s after it was zero ?

A sinusoidal ac current flows through a resistor of resistance R . If the peak current is I_(p) , then the power dissipated is

If the peak value of a current in 50Hz AC. Cirucit is 7.07 A. What is the mean value of current over half a cycle and the value of current 1//300 s after it was zero?

If an AC produces same heat as that produced by a steady current of 4 A , then peak value of current is :

What is the average value of a.c. over a full cycle ?
