Expression for electric potential
WebThe answer for electric field amplitude can then be written down immediately for a point outside the sphere, labeled Eout, and a point inside the sphere, labeled Ein. Eout = 1 4πε0 qtot r2, qtot = 4 3πR3ρ0, Ein = qenc 4πε0r2 = ρ0r 3ε0, sinceqenc = 4 3πr3ρ0. WebElectric potential, denoted by V (or occasionally φ), is a scalar physical quantity that describes the potential energy of a unit electric charge in an electrostatic field. Va = Ua/q It is defined as the amount of work energy needed to move a unit of electric charge from a reference point to a specific point in an electric field.
