AC Basics: Peak, RMS & Average Values

In an A.C. circuit, IrmsI_{\text{rms}} and I0I_0 are related as

Show answer and solution

Answer: (d)

  1. For sinusoidal current, mean of sin⁡2ωt\sin^2\omega t over a cycle is 12\frac{1}{2}.
  2. Irms=I022=I02I_{rms} = \sqrt{\frac{I_0^2}{2}} = \frac{I_0}{\sqrt{2}}
  3. So the answer is (d) Irms=I0/2I_{rms} = I_0/\sqrt{2}.
