What is a rms voltage?

Answer:

RMS is root mean square, it is defined as 1/sqrt(2) of the Peak - neutral voltage of a sine wave (no DC).

**************************************************************

The r.m.s. is the value of alternating voltage or current which gives the same heating effect as the same value of direct voltage or current.

What is RMS voltage?
rms voltage is a 'root mean square' voltage. This is used because every second amplitude of the voltage keeps varing between various peaks. Sometimes we also do refer to peak voltage also.
What is the conversion from RMS voltage to peak voltage?
The average voltage is the rms voltage. Volts peak = volts RMS times 1.414Volts RMS = volts peak times 0.7071Use the link below to an RMS voltage, peak voltage and peak-to-peak voltage...
What is voltage rms in relation to alternate voltage?
RMS voltage is the DC equivalent of your AC waveform. Vrms=(Vpeak)/(root two) If your peak voltage is 170V then the RMS voltage would be approx. 120 V (see related link)
How do you convert peak voltage to rms voltage?
RMS voltage is, for a sinusoidal waveform, is peak voltage divided by 2 times the square root of two, i.e. peak times 0.707. If you are talking peak-to-peak, you will need to divide by 2 one more...
What is the conversion for rms voltage to mean voltage?
For an alternating voltage, the simple mean over a cycle would be zero. 'RMS' means 'root mean square', and is defined as the square root of the mean value of the square of the voltage, taken over a...
