Electric potential difference gets a very special name. We call it voltage, measured it in units of volts, in honor of Alessandro Volta, the inventor of the battery. The voltage between points A and B is, Up to now the equations have all been in terms of electric potential difference. We talk about the potential difference between here and there.
Use the electric potential calculator to determine the electric potential at a point either due to a single point charge or a system of point charges. You can also use this tool to find out the electrical potential difference between two points.
Zero. The electric potential at a point P due to a charge q is inversely proportional to the distance between them. Hence, when the distance is infinite, the electric potential is zero. The electric potential calculator allows you to work out the electric potential at a point either due to a single point charge or a system of point charges.
