How to 转换 energy in joules (J) to electrical voltage in volts (V).
You can 计算 volts from joules and coulombs, but you can't 转换 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
求 the voltage supply of an electrical circuit with energy consumption of 60 joules and charge flow of 4 coulombs
V = 60J / 4C = 15V
