Calculate Voltage (Volts)
How to Convert Joules to Volts
Converting energy (Joules) directly to voltage (Volts) requires knowing the electric charge involved in the process. In physics, the relationship between these three units is defined by the work done to move a charge through an electric potential difference.
Joules to Volts Formula
The formula to calculate Voltage (V) from Energy (E) and Charge (Q) is:
V = {E}{Q}
Where:
- V = Voltage (Volts)
- E = Energy (Joules)
- Q = Electric Charge (Coulombs)
Volts to Joules Formula
Conversely, if you want to find the Energy in Joules based on Voltage and Charge, the formula is:
E = V \times Q
Definitions
Joule (J)The Joule is the derived unit of energy in the International System of Units. It is equal to the energy transferred to an object when a force of one newton acts on that object in the direction of the force’s motion through a distance of one meter.Volt (V)The Volt is the derived unit for electric potential, electric potential difference (voltage), and electromotive force. One Volt is defined as the difference in electric potential between two points of a conducting wire when an electric current of one ampere dissipates one watt of power between those points.Coulomb (C)The Coulomb is the unit of electric charge. One coulomb is equal to the quantity of electricity conveyed in one second by a current of one ampere.
