In particular, electrostatic forces are conservative. Consequently, it is more convenient to assign an electric potential energy U to describe any system of two or more charged particles. This idea allows us to define a scalar quantity known as the electric potential. It turns out that this concept is of great practical value when dealing with devices such as capacitors, resistors, inductors, batteries, etc, and when dealing with the flow of currents in electric circuits.enElectric PotentialPoint ChargeElectric Dipole MomentSurface Charge DensityElectrostatic Precipitator
