๐ก How to Convert Volts to Joules
Formula
J = V ร C
Where J = energy (joules), V = voltage (volts), C = charge (coulombs)
Example: 12V ร 10C = 120 joules
Where J = energy (joules), V = voltage (volts), C = charge (coulombs)
Example: 12V ร 10C = 120 joules
This formula comes from the definition of a volt: 1 volt = 1 joule per coulomb. It's used in capacitor energy calculations and physics problems.
