Enter the change in electric potential (volts) and the charge (C) into the calculator to determine the Voltage from Energy and Charge. 

Voltage from Energy and Charge Formula

The following formula is used to calculate the Voltage from Energy and Charge. 

dV = dPE / q
  • Where dV is the Voltage from Energy and Charge (volts)
  • dPE is the change in electric potential (volts) 
  • q is the charge (C) 

To calculate the voltage from energy and charge, divide the change in electric potential by the charge.

How to Calculate Voltage from Energy and Charge?

The following two example problems outline how to calculate the Voltage from Energy and Charge.

Example Problem #1:

  1. First, determine the change in electric potential (volts). In this example, the change in electric potential (volts) is measured to be 43.
  2. Next, determine the charge (C). For this problem, the charge (C) is calculated to be 3.
  3. Finally, calculate the Voltage from Energy and Charge using the formula above: 

dV = dPE / q

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

dV = 43 / 3 = 14.33 (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:

change in electric potential (volts) = 57

charge (C) = 7

Entering these values into the formula above gives : 

dV = 57 / 7 = 8.14 (volts)
