  2. Saturation current - Wikipedia

    en.wikipedia.org/wiki/Saturation_current

    The saturation current (or scale current), more accurately the reverse saturation current, is the part of the reverse current in a semiconductor diode caused by diffusion of minority carriers from the neutral regions to the depletion region. This current is almost independent of the reverse voltage.

  3. Saturation (magnetic) - Wikipedia

    en.wikipedia.org/wiki/Saturation_(magnetic)

    Varying the current in the control winding moves the operating point up and down on the saturation curve, controlling the alternating current through the inductor. These are used in variable fluorescent light ballasts, and power control systems. [11] Saturation is also exploited in fluxgate magnetometers and fluxgate compasses.

  4. Theory of solar cells - Wikipedia

    en.wikipedia.org/wiki/Theory_of_solar_cells

    The effect of reverse saturation current on the I-V curve of a crystalline silicon solar cell are shown in the figure to the right. Physically, reverse saturation current is a measure of the "leakage" of carriers across the p–n junction in reverse bias.

  5. Photocurrent - Wikipedia

    en.wikipedia.org/wiki/Photocurrent

    Photocurrent is the electric current through a photosensitive device, such as a photodiode, as the result of exposure to radiant power.The photocurrent may occur as a result of the photoelectric, photoemissive, or photovoltaic effect.

  6. Saturable reactor - Wikipedia

    en.wikipedia.org/wiki/Saturable_reactor

    A saturable reactor in electrical engineering is a special form of inductor where the magnetic core can be deliberately saturated by a direct electric current in a control winding. Once saturated, the inductance of the saturable reactor drops dramatically. [1] This decreases inductive reactance and allows increased flow of the alternating ...

  7. Air gap (magnetic) - Wikipedia

    en.wikipedia.org/wiki/Air_gap_(magnetic)

    Without saturation the inductance (and thus the blocking capability) of a choke stays constant regardless of the DC current flowing; [2] counter-intuitively, if a DC magnetization is present in an inductor, an increased (up to some limit) air gap actually incrementally increases the effective inductance ; [ 3 ]

  8. Faraday's law of induction - Wikipedia

    en.wikipedia.org/wiki/Faraday's_law_of_induction

    This field causes, by electromagnetic induction, an electric current to flow in the wire loop on the right. The most widespread version of Faraday's law states: The electromotive force around a closed path is equal to the negative of the time rate of change of the magnetic flux enclosed by the path.

  9. Current–voltage characteristic - Wikipedia

    en.wikipedia.org/wiki/Current–voltage...

    A current–voltage characteristic or I–V curve (current–voltage curve) is a relationship, typically represented as a chart or graph, between the electric current through a circuit, device, or material, and the corresponding voltage, or potential difference, across it.
