## 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

To calculate the peak voltage, multiply the the root-mean-square voltage by the square root of 2.

## 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

**What is peak voltage?**

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.

**What is RMS?**

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.
