Enter the individual voltages (volts) into the calculator to determine the Total Voltage. 

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:

  1. First, determine the individual voltages (volts). In this example, the individual voltages (volts) is measured to be 10 and 5.
  2. 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)
