## Voltage from Watts Formula

The following formula is used to calculate the Voltage from Watts.

**V = W / A**

Variables:

- Where V is the Voltage from Watts (volts)
- W is the total number of watts (watts)
- A is the total current (amps)

## How to Calculate Voltage from Watts?

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

**Example Problem #1:**

- First, determine the total number of watts (watts). In this example, the total number of watts (watts) is measured to be 31.
- Next, determine the total current (amps). For this problem, the total current (amps) is calculated to be 20.
- Finally, calculate the Voltage from Watts using the formula above:

V = W / A

Inserting the values from above into the equation yields:

V = 31 / 20 = 1.55 (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 number of watts (watts) = 10

total current (amps) = 60

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

V = 10 / 60 = .166 (volts)
