Enter the electrical load (watts) and the total current (amps) into the calculator to determine the Voltage from Load. 

Voltage from Load Formula

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

V = EL / I 


  • Where V is the Voltage from Load (volts)
  • EL is the electrical load (watts) 
  • I is the total current (amps) 

To calculate voltage from load, divide the total load by the total current.

How to Calculate Voltage from Load?

The following two example problems outline how to calculate the Voltage from Load.

Example Problem #1:

  1. First, determine the electrical load (watts). In this example, the electrical load (watts) is measured to be 7.
  2. Next, determine the total current (amps). For this problem, the total current (amps) is calculated to be 6.
  3. Finally, calculate the Voltage from Load using the formula above: 

V = EL / I 

Inserting the values from above and solving the equation with the imputed values gives: 

V = 7 / 6  = 1.1666 (volts)

Example Problem #2: 

Using the same process as example problem 1, we first define the variables outlined by the formula. In this case, the values are:

electrical load (watts) = 4

total current (amps) = 10

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

V = 4 / 10  = .40 (volts)
