## 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)

## 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:**

- First, determine the change in electric potential (volts). In this example, the change in electric potential (volts) is measured to be 43.
- Next, determine the charge (C). For this problem, the charge (C) is calculated to be 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)
