Calculating Vms?

Question

How do i calc the voltage mean square?

Answer 1

The RMS of a sinewave is .707 times the zero to peak voltage.

Answer 2

Do you mean VRMS?

There is no such thing as Vms, as it's not a voltage, it's a voltage squared.

VRMS is, in theory, done by first, squaring the waveform, then averaging it, then taking the square root.
