electric charge
noun
- one of the basic properties of the elementary particles of matter giving rise to all electric and magnetic forces and interactions. The two kinds of charge are given negative and positive algebraic signs: measured in coulombs.
electric charge
electric charge
- A form of charge, designated positive, negative, or zero, found on the elementary particles that make up all known matter. Particles with electric charge interact with each other through the electromagnetic force , creating electric fields, and when they are in motion, magnetic fields. The electric fields tend to result in a repulsive force between particles with charges of the same sign, and an attractive force between charges of opposite sign. The electron is defined to have an electric charge of −1; the protons in an atomic nucleus have charge of +1, and the neutrons have charge of 0.
