How to convert energy in joules (J) to electrical voltage in volts (V).
You can 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
volt = joule / coulomb
or
V = J / C
What is the voltage supply of an electrical circuit with energy consumption of 60 joules and charge flow of 4 coulombs?
V = 60J / 4C = 15V
