Electric Field Potential Calculator

The online calculator for calculating the potential of the electric field at a given point helps you to calculate the potential φ if you know: the charge q and the potential energy W of the charge q, and also the potential of the electric field ? created by the point charge Q and gives a step by step solution. Units of measurement can include any Si prefix. The calculator automatically converts one unit to another.

The calculator calculates:
Electric field potential if known: charge and potential energy of the charge.
Potential of the electric field created by a point charge.


Potential of Electric Field φ f Known: Charge q and Potential Energy W of Charge q

Potential of Electric FieldThe potential of the electric field ? at a given point is a scalar value equal to the ratio of the potential energy W of the charge q placed at a given point to the value of this charge. The unit of measurement for potential is Volt (V). The volt is equal to the potential of the field point at which the charge of 1 Coulomb has a potential energy of 1 Joule.
Potential energy W =
Charge q =
The SI unit of potential φ

The Potential of the Electric Field φ Created by a Point Charge Q

Potential of Electric FieldThe potential of the electric field ? created by a point charge Q is determined by the ratio of the electrostatic constant k multiplied by the charge Q to the distance r from the charge Q, where k = 8.9875517873681764 × 109. The unit of measurement of the potential is - Volt (V). The volt is equal to the potential of the field point at which the charge of 1 Coulomb has a potential energy of 1 Joule.
