Coulomb's Constant

Tags: Constant Electrical Magnetic

Coulomb constant, abbreviated as \(k_e, k, or K\), is the electric force constant, or the electrostatic constant, it is a proportionality constant in electrostatics equations.  When charged particles interact, a force repels or attracts the particles.
