Volts to Coulombs Calculator
Calculate electrical charge in Coulombs from voltage and energy in Joules.
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.
