Volts to joules calculator

Volts to joules estimation formula

E_(J) = V_(V) × Q_(C)

The energy E in joules (J) is equivalent to the voltage V in volts (V), duplicated by the electrical charge Q in coulombs (C).

So,

J = V x C
joule = volt × coulomb

For example:

Voltage (V) = 20V
Electrical charge (Q) = 3C

Energy (E) = 20V x 3C = 60J
