peak voltage is the highest level of volts giving from an alternating current. for example, in the UK the mains supply to a house is 230RMS. 230 is the average (simplified so bear with me) volts you will get from the AC supply. but in reality the AC wave is switching between -320 and 320 volts. so 320 is the peak voltage. to find out the peak voltage of an alternating current you must multiply the RMS voltage by root2 or 0.707 (this only works when the AC signal is a sine wave)
Totally wrong! Multiply the RMS voltage by 0.707 to find the PEAK voltage? What? The RMS voltage is 230. This times 0.707 is 163 which is far from the peak. Also 0.707 is not the sq. root of 2. I hope people don't take these answers seriously.
Peak Voltage is roughly 1.41 times the RMS voltage. (1.41 being the square root of 2) So 230 RMS mains voltage has a peak value of roughly 325V, (1.41x230). The original poster has accidentally multiplied the RMS value by 1 over the square root of 2 (0.707) ... which is what you multiply the peak value by in order to calculate the RMS.
The highest and lowest points on a voltage waveform.
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.
Usually with an oscilloscope which shows a graph of the voltage, and then the peak-to-peak ripple voltage can be read off the screen.
Peak value is 1.414 times the RMS voltage. On a 240 volt circuit the peak voltage is 240 x 1.414 = 339.36 volts. The peak to peak value is twice this.
rms stands for root mean squared. rms voltage is a way of measuring a sort of average alterating current voltage as distinguished from peak-to-peak voltage. Likewise for ac rms current.
Perhaps you are asking how the voltage of alternating current is measured, to be equivalent to the voltage of a direct current system. Alternating current and direct current have distinct properties. With direct current, voltage is at a constant polarity, and a direct current voltage source will maintain a uniform, constant voltage level. Alternating current reverses polarity at a given frequency and therefore it's voltage continuously varies from a positive peak voltage level, through zero, to a negative peak voltage level, repeating this cycle continuously. For this reason, voltage of an alternating current system, is measured in root-mean-square (rms), which is a voltage, which when multiplied by the current in amperes, calculates power which is equivalent to that of direct current of the same voltage and current values. With a typical sinusoidal waveform, the peak voltage of alternating current is divided by the square root of 2 to determine the rms voltage. The 120 volts output in the wall outlet in our home is actually about 170 peak volts.
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.
You measure the peak to peak voltage and divide by 2.
Simply multiply the peak voltage to 2 and you will get the peak to peak voltage.
ANSWER: The peak to peak voltage can be found by multiplying 120 v AC x 2.82= 339.41
A: Peak voltage is RMS multiplied by a factor of 1.41
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.
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.
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".
When the peak voltage is 311, the RMS voltage is 220. (311 * square root (2))
No, the peak-to-peak voltage is 2sqrt(2) times as much as the rms for a pure sine-wave.
