Scalar potential and electric field
WebThe electric field is a measure of the force that is exerted per coulomb of charge. Its measure is defined as kq/r 2 where k is the electrostatic constant constant, q is the amount of charge, and r is the distance between charges. The presence of an electric field is … WebThe curl-freeness of the vector field E → + A → ˙ (in a simply connected domain) implies the existence of a scalar potential with E → + A → ˙ = − grad φ and that is your formula. You see φ is just defined in the way you wrote it down. The purpose of introducing A → is to solve div B → = 0 and the purpose of introducing φ is to solve Faraday's law.
