Volts to Joules calculation formula The energy E in joules (J) is equal to the voltage V in volts (V) times the electrical charge Q in coulombs (C): E_{(J)} = V_{(V)} * Q_{(C)} |
NOTE: It is possible to calculate joules from volts and coulombs, but you cannot convert volts to joules since volt and joule units represent different quantities.Joules = Volts / Coulombs or J = V / C ExampleFind the energy in joules that is consumed in an electrical circuit with a voltage supply of 15V and a charge flow of 4 coulombs. E = 15V * 4C = 60J |
