## Rectifier Voltage Formula

The following formula is used to calculate the Rectifier Voltage.

Vr = 2*Vm / pi

Variables:

- Where Vr is the Rectifier Voltage (volts)
- Vm is the maximum or peak voltage (volts)

To calculate the rectifier voltage, multiply the peak voltage by 2, then divide by pi.

## How to Calculate Rectifier Voltage?

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

**Example Problem #1:**

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

Vr = 2*Vm / pi

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

Vr = 2*37/ 3.14159 = 23.55 (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:

maximum or peak voltage (volts) = 40

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

Vr = 2*40 / 3.14159 = 25.464 (volts)
