Elementary charge the difference between the particle "electron" and the unit of charge "electron" was still blurred. Later, the name "electron" was assigned to the particle and the unit of charge "e" lost its name. However, the unit of energy electronvolt reminds us that the elementary charge was once called "electron". The maximum capacity of each pixel in a charge-coupled device image sensor, known as the "well depth", is typically given in units of electrons, commonly around 10 per pixel. In high-energy physics (HEP) Lorentz–Heaviside units are used, and the charge unit is a dependent one, formula_1, so that = 0.30282212088 .
Charge (physics) a particular representation of that symmetry; the charge quantum number is then the weight of the representation. Various charge quantum numbers have been introduced by theories of particle physics. These include the charges of the Standard Model: Charges of approximate symmetries: Hypothetical charges of extensions to the Standard Model: In supersymmetry: In conformal field theory: In gravitation: In the formalism of particle theories, charge-like quantum numbers can sometimes be inverted by means of a charge conjugation operator called C. Charge conjugation simply means that a given symmetry group occurs in two inequivalent (but still isomorphic) group representations. It is usually
