An electric field is a vector field that is created by electrically charged particles, such as electrons and protons. It describes the influence or force experienced by other charged particles in the presence of an electric charge. The electric field is represented by a set of vectors that indicate the direction and magnitude of the force that a positively charged test particle would experience if placed at any given point within the field. The strength of an electric field at a specific location is determined by the magnitude and distribution of the electric charges that created it.
