Answer 2

Given,

Maximum value of sine wave of AC voltage =10V

To Find,

RMS value of sine wave.

Solution,

Maximum value of sine wave of AC voltage is 10V.
To calculate RMS value we have to divide the maximum value with √2.

So RMS value will be=Vmax/√2

                                   =10/√2
                                   =10/1.414
                                    =7.070V

Hence, the RMS value will be 7.070V.
