"It is the energy per unit charge for a test charge that is so small that the disturbance of the field under consideration is negligible."
"By definition, the electric potential at the reference point is zero units."
"Typically, the reference point is earth or a point at infinity, although any point can be used."
"The electrostatic potential, which is a scalar quantity denoted by V or occasionally Ļ, is equal to the electric potential energy of any charged particle at any location divided by the charge of that particle."
"This value can be calculated in either a static (time-invariant) or a dynamic (time-varying) electric field at a specific time with the unit joules per coulomb (Jā Cā1) or volt (V)."
"In electrodynamics, when time-varying fields are present, the electric field cannot be expressed only in terms of a scalar potential. Instead, the electric field can be expressed in terms of both the scalar electric potential and the magnetic vector potential."
"The electric potential and the magnetic vector potential together form a four-vector, so that the two kinds of potential are mixed under Lorentz transformations."
"The electric potential is a continuous function in all space because a spatial derivative of a discontinuous electric potential yields an electric field of impossibly infinite magnitude."
"The electric potential due to an idealized point charge (proportional to 1 ā r, with r the distance from the point charge) is continuous in all space except at the location of the point charge."
"Though the electric field is not continuous across an idealized surface charge, it is not infinite at any point. Therefore, the electric potential is continuous across an idealized surface charge."
"An idealized line of charge has electric potential (proportional to ln(r), with r the radial distance from the line of charge) that is continuous everywhere except on the line of charge."
