Conservation of electric energy

2026-10-01T13:10:50.446740

When a charged particle moves between two locations with different electric potentials, the resulting change in the electric potential energy of the particle-field system can be found by multiplying the charge by the electric potential difference between the locations. Assuming no resistive forces, the movement of a charged particle between two points with different electric potentials results in a change in kinetic energy of the particle consistent with the conservation of energy. An electron volt (eV) is a unit of energy equal to the kinetic energy gained by an electron or proton when it accelerates through a potential difference of one volt under the electric force alone.
