If you know that a waveform is sinusoidal,
and if you know the RMS value of the voltage,
the peak value of the voltage would be sqrt(2)
times the RMS voltage.
But the power actually used depends on
what devices are connected at any given time.
You can add up the watts without regard to
the shape of the voltage.
No. It's just measured in watts.
RMS voltage of an AC waveform is the DC voltage that would dissipate the same power in a resistance
No, power is an average value. The term RMS power is meaningless.
YES, VA is the proper unit for AC power where V is Vrms.
if not, then why??
