## Voltage from Power Factor Formula

The following formula is used to calculate the Voltage from Power Factor.

**V = W/PF/A**

- Where V is the Voltage from Power Factor (volts)
- PF is the power factor
- W is the watts
- A is the amps

## How to Calculate Voltage from Power Factor?

The following example problems outline how to calculate Voltage from Power Factor.

**Example Problem #1**

- First, determine the power factor. In this example, the power factor is determined to be 673 .
- Next, determine the watts. For this problem, the watts is measured to be 35 .
- Next, determine the amps. In this case, the amps is found to be 43.
- Finally, calculate the Voltage from Power Factor using the formula above:

V = W/PF/A

Inserting the values from above and solving yields:

V = 35/673/43 = .00120 (volts)

**Example Problem #2**

Using the same method as above, determine the variables required by the formula. For this example problem, these are:

power factor = 2

watts = 500

amps = 435

Enter these given values into the calculator or above yields:

V = 2/500/435 = .574** **(volts)
