How to convert Joules to Volts: The voltage V in volts (V) is equal to the energy E in joules (J) divided by the charge Q in coulombs (C): V_{(V)} = E_{(J)} / Q_{(C)} |
NOTE: It is possible to calculate volts from joules and coulombs, but you can't convert joules to volts since volt and joule units represent different quantities. The voltage V in volts (V) is equal to the energy E in joules (J) divided by the charge Q in coulombs (C): V_{(V)} = E_{(J)} / Q_{(C)} So Volts = Joules / Coulombs or V = J / C |
Example Find the voltage supply of an electrical circuit with an energy consumption of 60 joules and a charge flow of 4 coulombs. V = 60J / 4C = 15V |
