Carga elétrica ( AO 1945: carga eléctrica) é uma propriedade física fundamental que determina as interações eletromagnéticas. Esta carga está armazenada em grande quantidade nos corpos ao nosso redor, mas a percepção dela não ocorre facilmente.
Electric charge is a basic property of electrons, protons and other subatomic particles. Electrons are negatively charged while protons are positively charged. Things that are negatively charged and things that are positively charged pull on (attract) each other.
Electricity is the set of physical phenomena associated with the presence and motion of matter possessing an electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations.
