Electrical potential difference is the difference in the amount of potential energy a particle has due to its position between two locations in an electric field. Electric potential is a simple way of quantifying the potential energy that an electric particle has as a result of its location in an electric field. This is similar to how we talk about objects with mass and their potential energy as a result of their location in a gravitational field. read less

The electric potential difference is the difference in electric potential (V) between the final and the initial location when work is done upon a charge to change its potential energy. The standard metric unit on electric potential difference is the volt, abbreviated V and named in honor of Alessandro Volta. One Volt is equivalent to one Joule per Coulomb. If the electric potential difference between two locations is 1 volt, then one Coulomb of charge will gain 1 joule of potential energy when moved between those two locations. read less

The difference between two electrodes.Need not to be one positive and one is negative.It can be the difference between higher and lower points electrical pressure or electrical tension.potential difference is expressed in units of volts, it is sometimes referred to as the voltage(v).

The potential difference is defined as the amount of work done in moving a unit positive charge from one point to another point. SI unit- Volt (V)

It is amount of work done in moving a unit charge from one point to the other point. Potential difference =work done/quantity of charge moved. Its SI unit is volt. 1 volt is defined as if 1 joule of work is done in moving 1 coulomb of electric charge from one point to the other.
