## Effective Voltage Formula

The following formula is used to calculate the Effective Voltage.

Veff = Vp / SQRT(2)

Variables:

- Where Veff is the Effective Voltage (volts)
- Vp is the peak voltage (volts)

To calculate the effective voltage, divide the peak voltage by the square root of 2.

## How to Calculate Effective Voltage?

The following two example problems outline how to calculate the Effective Voltage.

**Example Problem #1:**

- First, determine the peak voltage (volts). In this example, the peak voltage (volts) is measured to be 37.
- Finally, calculate the Effective Voltage using the formula above:

Veff = Vp / SQRT(2)

Inserting the values from above and solving the equation with the imputed values gives:

Veff = 37 / SQRT(2) = 26.162 (volts)

**Example Problem #2: **

Using the same process as example problem 1, we first define the variables outlined by the formula. In this case, the values are:

peak voltage (volts) = 1000

Entering these values into the formula or calculator above gives us::

Veff = 1000 / SQRT(2) = 707.106 (volts)
