Peak Voltage Formula
The following formulas are used to calculate peak voltage from average or RMS voltage.
Vp = Vrms * Sqrt(2)
- Where Vp is the peak voltage
- Vrms is the RMS (root-mean-square) voltage
Vp = Vave * Pi/2
- Where Vp is the peak voltage
- Vave is the average voltage
Peak Voltage Definition
A peak voltage is the maximum value of the voltage of a sinusoidal voltage wave.
How to calculate peak voltage?
How to calculate peak voltage
- First, determine which voltage value you will use
Voltage is typically measured as a sinusoidal function. As a result, the voltage varies over time. To measure the average of this variation, either the average voltage or the RMS (root-mean-square) voltage.
- Choose the correct formula
Next, depending on your voltage measurement in step 1, chose the formula needed to calculate peak voltage.
- Calculate Peak Voltage
Calculate the peak voltage using the equation or calculator above.
FAQ
Since voltage is not constant, but rather varies along with a sinusoidal wave, typically the average voltage is measured. However, this voltage will have peaks and valleys as it travels along that wave. Therefore, the peak voltage is the max voltage a voltage wave sees.
RMS stands for root-mean-square and is exactly as it sounds. It’s the root of the square-mean. It’s very similar to the average of a set of data.
