## DC Voltage from AC Voltage Formula

The following formula is used to calculate the DC Voltage from AC Voltage.

Vdc = Vac * .636

Variables:

- Where Vdc is the DC Voltage from AC Voltage (volts)
- Vac is the total alternating current voltage (volts)

To calculate DC voltage from AC voltage, multiply the AC voltage by .636.

## How to Calculate DC Voltage from AC Voltage?

The following two example problems outline the steps and information needed in order to calculate the DC Voltage from AC Voltage.

**Example Problem #1:**

- First, determine the total alternating current voltage (volts). In this example, the total alternating current voltage (volts) is measured to be 60.
- Finally, calculate the DC Voltage from AC Voltage using the formula above:

Vdc = Vac * .636

Inserting the values from above into the equation yields:

Vdc = 60 * .636 = 38.16 (volts)

**Example Problem #2: **

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

total alternating current voltage (volts) = 11

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

Vdc = 11 * .636 = 6.996 (volts)
