Question
If I1, I2, I3 and I4 are the respective r.m.s. values of the time varying currents as shown in the four cases I, II, III and IV. Then identify the correct relations
Options
A.I1 = I2 = I3 = I4
B.I3 > I1 = I2 > I4
C.I3 > I4 > I2 = I1
D.I3 > I2 > I1 > I4
Solution
Irms =
I02 sin ωt Rdt ⇒ I1 = I2
and current In the I3 more than I1 = I2
I3 > I1 = I2 > I4
I02 sin ωt Rdt ⇒ I1 = I2and current In the I3 more than I1 = I2
I3 > I1 = I2 > I4
