How to Convert Volts to Coulombs

C = J ÷ V

C = Charge (coulombs)

J = Energy (joules)

V = Voltage (volts)

Practical Example

Given:

• Energy = 12 joules
• Voltage = 3 volts

Solution:

C = 12 J ÷ 3 V = 4 C

Explanation of Terms

• C (Coulombs): The unit of electric charge. One coulomb is defined as the amount of charge transported by a constant current of one ampere in one second.
• J (Joules): The unit of energy. One joule is the energy transferred when one newton of force is applied over a distance of one meter.
• V (Volts): The unit of electric potential difference. One volt is defined as the potential difference that will move one ampere of current against one ohm of resistance.
