Electrostatics - Definition, Example & Explanation - Vedantu

The electric field, , in units of newtons per coulomb or volts per meter, is a vector field that can be defined everywhere, except at the location of point charges (where it diverges to infinity). It is defined as the electrostatic force in newtons on a hypothetical small test charge at the point due to Coulomb's Law, divided by the magnitude of the charge in coulombs Electric field lines are useful for visualizing the electric field. Field lines begin on positive charge … WebbThis equation is a special case of Poisson’s equation div grad V = ρ, which is applicable to electrostatic problems in regions where the volume charge density is ρ.
