  2. Displacement current - Wikipedia

    en.wikipedia.org/wiki/Displacement_current

    In electromagnetism, displacement current density is the quantity ∂D/∂t appearing in Maxwell's equations that is defined in terms of the rate of change of D, the electric displacement field.

  3. Drift current - Wikipedia

    en.wikipedia.org/wiki/Drift_current

    Drift current is the electric current caused by particles getting pulled by an electric field. The term is most commonly used in the context of electrons and holes in semiconductors, although the same concept also applies to metals, electrolytes, and so on.

  4. Electric current - Wikipedia

    en.wikipedia.org/wiki/Electric_current

    An electric current is a flow of charged particles, such as electrons or ions, moving through an electrical conductor or space. It is defined as the net rate of flow of electric charge through a surface.

  5. Diffusion current - Wikipedia

    en.wikipedia.org/wiki/Diffusion_current

    Diffusion current is a current in a semiconductor caused by the diffusion of charge carriers (electrons and/or electron holes).This is the current which is due to the transport of charges occurring because of non-uniform concentration of charged particles in a semiconductor.

  6. Direct current - Wikipedia

    en.wikipedia.org/wiki/Direct_current

    Brush Electric Company's central power plant with dynamos generating direct current to power arc lamps for public lighting in New York. Beginning operation in December 1880 at 133 West Twenty-Fifth Street, the high voltages it operated at allowed it to power a 2-mile (3.2 km) long circuit.

  7. Ampere - Wikipedia

    en.wikipedia.org/wiki/Ampere

    The ampere is named for French physicist and mathematician André-Marie Ampère (1775–1836), who studied electromagnetism and laid the foundation of electrodynamics.In recognition of Ampère's contributions to the creation of modern electrical science, an international convention, signed at the 1881 International Exposition of Electricity, established the ampere as a standard unit of ...

  8. Short circuit - Wikipedia

    en.wikipedia.org/wiki/Short_circuit

    A short circuit is an abnormal connection between two nodes of an electric circuit intended to be at different voltages. This results in an electric current limited only by the Thévenin equivalent resistance of the rest of the network which can cause circuit damage, overheating, fire or explosion.

  9. Electric generator - Wikipedia

    en.wikipedia.org/wiki/Electric_generator

    U.S. NRC image of a modern steam turbine generator (STG). In electricity generation, a generator [1] is a device that converts motion-based power (potential and kinetic energy) or fuel-based power (chemical energy) into electric power for use in an external circuit.
