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)


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

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)
