The SI derived unit of electric potential is the volt (in honor of Alessandro Volta), denoted as V, which is why the electric potential difference between two points in space is known as a voltage. Older units are rarely used today. Variants of the centimetre–gram–second system of units included a number of … See more The electric potential (also called the electric field potential, potential drop, the electrostatic potential) is defined as the amount of work energy needed to move a unit of electric charge from a reference point to the specific … See more When time-varying magnetic fields are present (which is true whenever there are time-varying electric fields and vice versa), it is not possible to describe the electric field simply in terms of a scalar potential V because the electric field is no longer conservative See more • Absolute electrode potential • Electrochemical potential • Electrode potential See more Classical mechanics explores concepts such as force, energy, and potential. Force and potential energy are directly related. A net force acting on any object will cause it to See more The electric potential at a point r in a static electric field E is given by the line integral where C is an arbitrary path from some fixed reference point to r. In electrostatics, the See more Inside metals (and other solids and liquids), the energy of an electron is affected not only by the electric potential, but also by the … See more • Politzer P, Truhlar DG (1981).
