Question

The rms value of current for the following current time graph will be
​

Answer 1

Given ,

Peak value of AC $\sf{ (I_{o} })$ = 3 amp

As we know that ,

The root mean square (RMS) value of current is given by

$\boxed{ \sf{I_{RMS} = \frac{I_{o}}{ \sqrt{2} } }}$

Thus ,

RMS value of curent = 3/√2 Amp

∴The correct option is (A)
