Enter the energy and electric charge into the calculator to determine the electric potential. This calculator can also evaluate any of the variables given the others are known.

## Coulombs To Volts Formula

The following formula is used to calculate the electric potential in volts from the electric charge in coulombs and energy in joules.

V = E / Q

Variables:

- V is the electric potential in volts (V)
- E is the energy in joules (J)
- Q is the electric charge in coulombs (C)

To calculate the electric potential in volts, divide the energy in joules by the electric charge in coulombs. This is based on the definition of a volt as one joule per coulomb.

## What is Coulombs To Volts?

Coulombs and volts are two different units used in the field of physics, specifically in electricity. Coulombs are a unit of electric charge, while volts are a unit of electric potential or electromotive force. There isn’t a direct conversion from coulombs to volts because they measure different things. However, they are related through the concept of electric potential energy, where one volt is defined as one joule (unit of energy) per coulomb. This means that if one coulomb of charge gains or loses one joule of energy, it has moved through a potential difference of one volt.

## How to Calculate Coulombs To Volts?

The following steps outline how to calculate the Coulombs To Volts using the formula: V = E / Q.

- First, determine the energy in joules (E).
- Next, determine the electric charge in coulombs (Q).
- Next, gather the formula from above = V = E / Q.
- Finally, calculate the electric potential in volts (V).
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem:**

Use the following variables as an example problem to test your knowledge.

energy in joules (E) = 150

electric charge in coulombs (Q) = 25
