Volts To Joules Converter

To calculate energy in joules, simply enter the voltage in volts and the electric charge in coulombs into the volts to joules converter. This calculator quickly converts volts to joules based on standard physics formulas and helps you understand how electrical energy works in circuits.

What Are Volts?

A volt (V) is the unit of electric potential difference or electromotive force. It defines the pressure that pushes electric charges through a conductor. The greater the voltage, the stronger the flow of electric current.

What Is a Joule?

A joule (J) is the SI unit of energy. It represents the amount of work done when a force of one newton moves an object one meter in the direction of the force. In electrical terms, it tells us how much energy is transferred by one coulomb of charge across one volt.

1 J = Kg·m²/s²

1 J = 1 N·m

Formula to Convert Volts to Joules

The basic formula used to convert volts to joules is:

Energy (J) = Voltage (V) × Charge (C)

• E = Energy in joules
• V = Voltage in volts
• Q = Electric charge in coulombs

Example Calculation

Let’s say we have a charge of 5 coulombs and a voltage of 12 volts.

• Energy = 12 V × 5 C
• Energy = 60 Joules

So, 5 coulombs of charge at 12 volts equals 60 joules of energy.

How to Convert Volts to Joules?

Suppose the voltage is 300V and the charge is 2C. To find the energy in joules:

Energy = 300 V × 2 C = 600 J

Therefore, 300 volts and 2 coulombs will produce 600 joules of energy.

FAQs

1. Is volts to joules conversion important?

Yes, it helps you calculate how much energy an electrical system is using or producing.

2. What is the relation between volts, joules, and coulombs?

Joules = Volts × Coulombs. This relation helps measure electrical energy.

3. Can I convert joules to volts?

Yes, if you have the charge in coulombs. Just rearrange the formula: Volts = Joules ÷ Coulombs.

4. What devices use this formula?

It’s commonly used in electronics, batteries, power supplies, and physics experiments.

E(J) = V(V) × Q(C)

• J = 300 * 2
• J = 600 joules
