How do you calculate resistance with coulombs, time and J's?

Hey user

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)

So

joule = volt * coulomb

or

J = V * C

Example

What is the energy in joules that is consumed in an electrical circuit with voltage supply of 15V and charge flow of 4 coulombs?

E = 15V * 4C = 60J
