  2. Electric charge - Wikipedia

    en.wikipedia.org/wiki/Electric_charge

    Electric charge is a conserved property: the net charge of an isolated system, the quantity of positive charge minus the amount of negative charge, cannot change. Electric charge is carried by subatomic particles. In ordinary matter, negative charge is carried by electrons, and positive charge is carried by the protons in the nuclei of atoms ...

    The elementary charge e, i.e. the negative charge on a single electron or the positive charge on a single proton [3] 10 −18: atto-(aC) ~ 1.8755 × 10 −18 C: Planck charge [4] [5] 10 −17: 1.473 × 10 −17 C (92 e) – Positive charge on a uranium nucleus (derived: 92 x 1.602 × 10 −19 C) 10 −16: 1.344 × 10 −16 C: Charge on a dust ...

  4. Charge carrier - Wikipedia

    en.wikipedia.org/wiki/Charge_carrier

    There are two recognized types of charge carriers in semiconductors.One is electrons, which carry a negative electric charge.In addition, it is convenient to treat the traveling vacancies in the valence band electron population as a second type of charge carrier, which carry a positive charge equal in magnitude to that of an electron.

  5. Charged particle - Wikipedia

    en.wikipedia.org/wiki/Charged_particle

    In physics, a charged particle is a particle with an electric charge. For example, some elementary particles, like the electron or quarks are charged. [1] Some composite particles like protons are charged particles. An ion, such as a molecule or atom with a surplus or deficit of electrons relative to protons are also charged particles.

  6. Elementary charge - Wikipedia

    en.wikipedia.org/wiki/Elementary_charge

    Charge quantization is the principle that the charge of any object is an integer multiple of the elementary charge. Thus, an object's charge can be exactly 0 e, or exactly 1 e, −1 e, 2 e, etc., but not ⁠ 1 / 2 ⁠ e, or −3.8 e, etc. (There may be exceptions to this statement, depending on how "object" is defined; see below.)

  9. Faraday's ice pail experiment - Wikipedia

    en.wikipedia.org/wiki/Faraday's_ice_pail_experiment

    A charged object outside any container also induces an equal charge on its surroundings. [12] [21] The field lines extending from it end on charges induced in the walls or other objects in the room. This illustrates the general principle that for every positive charge, there must be a corresponding negative charge somewhere in the universe.
