  2. LED circuit - Wikipedia

    is the desired current of the LED in amps. The maximum continuous-on current is shown on LED datasheets, for example 20 mA (0.020 A) is common for most small LEDs. Many circuits operate LEDs at less than the specified maximum current to save power, or to reduce brightness, or to use a common resistor value. For indoor use, tiny surface mount ...

  3. Light-emitting diode - Wikipedia

    en.wikipedia.org/wiki/Light-emitting_diode

    The current in an LED or other diodes rises exponentially with the applied voltage (see Shockley diode equation), so a small change in voltage can cause a large change in current. Current through the LED must be regulated by an external circuit such as a constant current source to prevent damage. Since most common power supplies are (nearly ...

    An LED begins to emit light when more than 2 or 3 volts is applied in the forward direction. The reverse bias region uses a different vertical scale from the forward bias region to show that the leakage current is nearly constant with voltage until breakdown occurs. In forward bias, the current starts small but increases exponentially with voltage.

    However, AWG is dissimilar to IEC 60228, the metric wire-size standard used in most parts of the world, based directly on the wire cross-section area (in square millimetres, mm 2). The AWG tables are for a single, solid and round conductor. The AWG of a stranded wire is determined by the cross-sectional area of the equivalent solid conductor.

  7. 16-pin 12VHPWR connector - Wikipedia

    en.wikipedia.org/wiki/16-Pin_12vHPWR_connector

    It was replaced by a minor revision called 12V-2x6, which changed the connector to ensure that the sense pins only make contact if the power pins are seated properly. The original connector was formally adopted as part of PCI Express 5.x, [ 1 ] while the revised 12V-2x6 connector design was adopted later.
