How rms voltage related to peak voltage?

Answer 1

The average voltage is the rms voltage.

Volts peak = volts RMS times 1.414

Volts RMS = volts peak times 0.7071

Use the link below to an RMS voltage, peak voltage and peak-to-peak voltage calculator.

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

The average voltage is not the r.m.s. voltage.

The average voltage of a sine wave is 0.636 x the peak value. Conversely, peak voltage is 1.57 the mean or average.

Answer 2

To convert from peak-to-peak voltage to RMS voltage for a sinusoidal waveform, divide by two times the square root of two, i.e. 2.828.

This assumes that the actual waveform is balanced around zero, i.e. that it goes equally plus and minus.

Answer 3

RMS is the 1/ 2*sqr (2) of the applied peak to peak voltage. Thus a ~340volt peak to peak (typical house voltage in US) is 120 VRMS.

This is true for AC waveforms. For a square wave the RMS value will be different. If you want further information on other RMS values, please ask again with the specific waveform you wish.

Answer 4

Normally, RMS voltage is .707 times peak voltage, as explained below.

RMS stands for "root mean square."

When discussing voltage, that is defined as the square root of the average of the square of the voltage.

The peak voltage is simply the highest value that the voltage attains.

The peak-to-peak voltage is the difference between the highest voltage and the lowest voltage.

Household power is generally AC, alternating current. It is always a sinusoidal current and voltage.

For household alternating currents, the voltages one encounters around the world are generally in the vicinity of 120 volts or 240 volts. Those numbers refer to the RMS voltage.

RMS voltage is, for a sinusoidal waveform, the peak voltage divided by the square root of two, i.e. peak times 0.707.

For household alternating currents, peak-to-peak voltage is just twice the peak voltage.

Answer 5

As peak voltage means peak value in one half cycle. If we double it we get peak to peak voltage.

Answer 6

simply pass the input signal through a rectifier(simple diode).

Answer 7

In a standard sine-wave the peak voltage is sqrt(2) times the rms.
