  2. Automotive battery - Wikipedia

    en.wikipedia.org/wiki/Automotive_battery

    An automotive battery, or car battery, is a rechargeable battery that is used to start a motor vehicle. Its main purpose is to provide an electric current to the electric-powered starting motor, which in turn starts the chemically-powered internal combustion engine that actually propels the vehicle. Once the engine is running, power for the car ...

  3. Parasitic load - Wikipedia

    en.wikipedia.org/wiki/Parasitic_load

    Parasitic load or parasitic loss may refer to. in internal combustion engines, it refers to devices that take energy from the engine in order to enhance the engine's ability to create more energy or convert energy to motion. in electrical appliances, it represents the power consumed even when the appliance is shut off. With regard to railway ...

  4. Failure of electronic components - Wikipedia

    en.wikipedia.org/wiki/Failure_of_electronic...

    Electronic components have a wide range of failure modes. These can be classified in various ways, such as by time or cause. Failures can be caused by excess temperature, excess current or voltage, ionizing radiation, mechanical shock, stress or impact, and many other causes. In semiconductor devices, problems in the device package may cause ...

  5. Standby power - Wikipedia

    en.wikipedia.org/wiki/Standby_power

    Standby power, also called vampire power[ 1], vampire draw, phantom load, ghost load or leaking electricity refers to the way electric power is consumed by electronic and electrical appliances while they are switched off (but are designed to draw some power) or in standby mode. This only occurs because some devices claimed to be "switched off ...

  6. Contact resistance - Wikipedia

    en.wikipedia.org/wiki/Contact_resistance

    Parasitic resistance is a more general term, of which it is usually assumed that contact resistance is a major component. William Shockley [1] introduced the idea of a potential drop on an injection electrode to explain the difference between experimental results and the model of gradual channel approximation.

  7. Automobile auxiliary power outlet - Wikipedia

    en.wikipedia.org/wiki/Automobile_auxiliary_power...

    An automobile auxiliary power outlet (also known as car cigarette lighter or auxiliary power outlet[ 1]) in an automobile was initially designed to power an electrically heated cigarette lighter, [ 1] but became a de facto standard DC connector to supply electrical power for portable accessories used in or near an automobile directly from the ...

  9. Insulated-gate bipolar transistor - Wikipedia

    en.wikipedia.org/wiki/Insulated-gate_bipolar...

    IGBT schematic symbol. An insulated-gate bipolar transistor ( IGBT) is a three-terminal power semiconductor device primarily forming an electronic switch. It was developed to combine high efficiency with fast switching. It consists of four alternating layers ( P–N–P–N) that are controlled by a metal–oxide–semiconductor (MOS) gate ...
