In an ac circuit, the r.m.s. value of current, Irms is related to the peak current, I0 by the relation [AFMC 2002]

A)            \[{{I}_{rms}}=\frac{1}{\pi }{{I}_{0}}\]                            

B)            \[{{I}_{rms}}=\frac{1}{\sqrt{2}}{{I}_{0}}\]

C)            \[{{I}_{rms}}=\sqrt{2}{{I}_{0}}\]                                      

D)            \[{{I}_{rms}}=\pi {{I}_{0}}\]
