## Total Voltage Formula

The following formula is used to calculate the Total Voltage.

Vtotal = SUM (Vx)

Variables:

- Where Vtotal is the Total Voltage (volts)
- Vx is the individual voltages (volts)

To calculate the total voltage, simply sum the individual voltages together.

## How to Calculate Total Voltage?

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

**Example Problem #1:**

- First, determine the individual voltages (volts). In this example, the individual voltages (volts) is measured to be 10 and 5.
- Finally, calculate the Total Voltage using the formula above:

Vtotal = SUM (Vx)

Inserting the values from above into the equation yields:

Vtotal = SUM (10 + 5) = 15 (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:

individual voltages (volts) = 40 , 20 , 10

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

Vtotal = SUM (40 + 20 + 10 ) = 70 (volts)
