NCERT · Class 12 · Physics · Alternating CurrentThe peak value of an alternating current is $I0$. Its root mean square (rms) value ($I{rms}$) is given by:
Step-by-Step Solution
The relation between the rms value and the peak value of alternating current is $I_{rms} = \frac{I_0}{\sqrt{2}} \approx 0.707 I_0$.
