Charge is a word with many different meanings.


In science, the concept of charge is derived from the observation of conserved quantum numbers. Various charge-like quantum numbers have been introduced by theories of particle physics, e.g. electric charge for electromagnetic interaction, magnetic charge (currently purely hypothetic), colour charge for gluons, quark charges like strangeness, and isospin for electroweak interactions. In the formalism of particle theories charge-like quantum numbers can be inverted by means of a charge operator called C.
