What is the approximate peak value of an alternating current producing four times the heat produced per second by a steady current of 2 A in a resistor

a) 2.8 A

b) 4.0 A

c) 5.6 A

d) 8.0 A

The answer given is 5.6 A .. explain how ?

Irms=Imax/1.414

Using the above 2 relations we can find out that,

Imax=2.828 Isteady

.

Imax=2.828*2=5.6 A
