Q7.2 (b) The RMS value of current in an ac circuit is 10\: A . What is the peak current?

Answers (1)

Given,

RMS value of current I_{rms}=10A

Since Current is also sinusoidal (because only resistance is present  in the circuit, not the capacitor and inductor)

I_{rms}=\frac{I_{peak}}{\sqrt{2}}

I_{peak}=\sqrt{2}I_{rms}=\sqrt{2}*10=14.1A

Hence the peak value of current is 14.1A.
