Electric Potential

#) Electric Potential: The electric potential (or simply potential) at a point in an electric field is defined as the work done in moving a unit positive charge from infinity to that point.

>> The electric potential at infinity is assumed to be zero. Force and potential energy are directly related.

>> This means that the work it does on a particle depends only on the initial and final position of the particle, and not on the path followed.

>> With each conservative force, a potential energy can be associated.

>> The introduction of the potential energy is useful since it allows us to apply conservation of mechanical energy which simplifies the solution of a large number of problems.
