A modern power grid consists of many voltages and currents, all being interconnected by Transformers, which trade off voltage and current. A typical power generator usually generates electricity at a few thousand volts AC, which is then stepped up to around 120kv for distribution, then stepped down to around 30kv, for secondary distribution, then finally down to 240v/120v for domestic use.

Engineers typically measure the voltage of AC circuits using "RMS voltages" (Root Mean Squared voltages) This convention is used because of the varying nature of AC, and relates the varying AC voltage to an effective DC voltage. RMS Voltage for typical AC =Peak voltage / Square root(2) which is approximately equal to peak voltage* 70%

What is peak to peak voltage?

Conversions of RMS voltage, peak voltage and peak-to-peak voltage. That are the used voltages. The expression "average" voltage is used for RMS voltage.Scroll down to related links and seach for "RMS voltage, peak voltage and peak-to-peak voltage".Answer'Average' is not the same as 'root mean square'. As the average value of a sinusoidal voltage is zero, you cannot convert it to a peak-to-peak value.


How do you measure peak voltage using oscilloscope?

You measure the peak to peak voltage and divide by 2.


How do you convert peak voltage to peak-peak voltage?

Simply multiply the peak voltage to 2 and you will get the peak to peak voltage.


What is the difference of peak and rms value?

RMS stands for "Root of the Means Squared", and is a mathematical method of defining the "operating" voltage of a sine wave power source. Typical home lighting and outlet voltage presently is 120 VAC (volts alternating current), 60 Hz. (Hertz, formerly referred to as "cycles per second".) But the PEAK voltage is the absolute maximum voltage at the "peak" of each sine wave of voltage. Mathematically, the "Peak" voltage is 1.414 (which is the square root of the number 2) times the RMS voltage, and conversely, the RMS voltage is 0.707 times the PEAK voltage.


What is the peak-to-peak voltage in a circuit with an rms voltage of 120VAC?

ANSWER: The peak to peak voltage can be found by multiplying 120 v AC x 2.82= 339.41


What is a peak load voltage out of a bridge rectifier for a secondary voltage of 15 Vrms?

A: Peak voltage is RMS multiplied by a factor of 1.41


What is average voltage?

Another name for average voltage is the RMS (Root Mean Square). This is a voltage derived from the peak to peak voltage multiplied by .707. If the peak to peak voltage is 170 volts then the average voltage (RMS) would be 170 x .707 = 120 volts.


How rms voltage related 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 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.


What is difference between amplitude and peak value?

It is the highest value of the amplitude, called the peak value. Scroll down to related links and look at "RMS voltage, peak voltage and peak-to-peak voltage". Look at the figure in the middle below the headline "RMS voltage, peak voltage and peak-to-peak voltage".


What is the effective voltage for a peak voltage of 311 volts?

When the peak voltage is 311, the RMS voltage is 220. (311 * square root (2))


Are peak-to-peak and rms voltage measurements the same?

No, the peak-to-peak voltage is 2sqrt(2) times as much as the rms for a pure sine-wave.


Why is the peak voltage not exactly equal to the peak voltage of the alernating voltage and by how much it differ?

If you are referring to the voltage after the rectifiers in a powersupply, it is due to the voltage drop across the rectifiers.
