  2. Ohm's law - Wikipedia

    en.wikipedia.org/wiki/Ohm's_law

    Ohm's law, in the form above, is an extremely useful equation in the field of electrical/electronic engineering because it describes how voltage, current and resistance are interrelated on a "macroscopic" level, that is, commonly, as circuit elements in an electrical circuit.

  3. Electric heating - Wikipedia

    en.wikipedia.org/wiki/Electric_heating

    30 kW resistance heating coils This radiant heater uses tungsten halogen lamps. Electric heating is a process in which electrical energy is converted directly to heat energy. Common applications include space heating, cooking, water heating and industrial processes. An electric heater is an electrical device that converts an electric current ...

  4. Silicon controlled rectifier - Wikipedia

    en.wikipedia.org/wiki/Silicon_controlled_rectifier

    SCR 4-layer (p-n-p-n) diagram. A silicon controlled rectifier or semiconductor controlled rectifier is a four-layer solid-state current-controlling device.The name "silicon controlled rectifier" is General Electric's trade name for a type of thyristor.

  5. Liquid rheostat - Wikipedia

    en.wikipedia.org/wiki/Liquid_rheostat

    A liquid rheostat or water rheostat or salt water rheostat is a type of variable resistor. This may be used as a dummy load or as a starting resistor for large slip ring motors. In the simplest form it consists of a tank containing brine or other electrolyte solution, in which electrodes are submerged to create an electrical load .

  6. Voltage-controlled oscillator - Wikipedia

    en.wikipedia.org/wiki/Voltage-controlled_oscillator

    A microwave (12–18 GHz) voltage-controlled oscillator. A voltage-controlled oscillator (VCO) is an electronic oscillator whose oscillation frequency is controlled by a voltage input. The applied input voltage determines the instantaneous oscillation frequency.

  7. Biasing - Wikipedia

    en.wikipedia.org/wiki/Biasing

    In electronics, biasing is the setting of DC (direct current) operating conditions (current and voltage) of an electronic component that processes time-varying signals. Many electronic devices, such as diodes , transistors and vacuum tubes , whose function is processing time-varying ( AC ) signals, also require a steady (DC) current or voltage ...

  8. Handkerchief code - Wikipedia

    en.wikipedia.org/wiki/Handkerchief_code

    The handkerchief code (also known as the hanky code, the bandana code, and flagging) [1] is a system of color-coded cloth handkerchief or bandanas for non-verbally communicating one's interests in sexual activities and fetishes. The color of the handkerchief identifies a particular activity, and the pocket it is worn in (left or right ...

  9. 78xx - Wikipedia

    en.wikipedia.org/wiki/78xx

    78xx (sometimes L78xx, LM78xx, MC78xx...) is a family of self-contained fixed linear voltage regulator integrated circuits. The 78xx family is commonly used in electronic circuits requiring a regulated power supply due to their ease-of-use and low cost.
