Joules (J) to Volts (V) calculator
Joules (J) to Volts (V) conversion
Convert energy in joules (J) to electrical voltage in volts (V)
The voltage V, in Volts (V) across an electrical circuit is calculated by dividing the Energy E, in Joules (J) by the Charge Q in coulomb (C).
V(V) = E(J) / Q(C)
Therefore;
Volt = joule / coulomb
Or
V = J / C
Example
If the energy consumption in an electrical circuit is 90 Joules and the charge flowing through the circuit is 3 coulombs, calculate the voltage supply across the circuit.
Solution
V = 90J / 3C = 30V
