2. Infinite switch - Wikipedia

   en.wikipedia.org/wiki/Infinite_switch

   An infinite switch, simmerstat, energy regulator or infinite controller is a type of switch that allows variable power output of a heating element of an electric stove. It is called "infinite" because its average output is infinitely variable rather than being limited to a few switched levels. It uses a bi-metallic strip conductive connection ...

3. List of resistors - Wikipedia

   en.wikipedia.org/wiki/List_of_resistors

   Variable resistors can be used to adjust circuit elements (such as a volume control or a lamp dimmer), or as sensing devices for heat, light, humidity, force, or chemical activity. Resistors are common elements of electrical networks and electronic circuits and are ubiquitous in electronic equipment. Practical resistors as discrete components ...

4. Kanthal (alloy) - Wikipedia

   en.wikipedia.org/wiki/Kanthal_(alloy)

   Kanthal (alloy) Kanthal is the trademark for a family of iron-chromium-aluminium (FeCrAl) alloys used in a wide range of resistance and high-temperature applications. Kanthal FeCrAl alloys consist of mainly iron, chromium (20–30%) and aluminium (4–7.5 %). The first Kanthal FeCrAl alloy was developed by Hans von Kantzow in Hallstahammar, Sweden.

5. Current sensing - Wikipedia

   en.wikipedia.org/wiki/Current_sensing

   In electrical engineering, current sensing is any one of several techniques used to measure electric current. The measurement of current ranges from picoamps to tens of thousands of amperes. The selection of a current sensing method depends on requirements such as magnitude, accuracy, bandwidth, robustness, cost, isolation or size.

6. Induction coil - Wikipedia

   en.wikipedia.org/wiki/Induction_coil

   Invented. 1836 (188 years ago) (1836) Induction coil showing construction, from 1920. An induction coil or "spark coil" (archaically known as an inductorium or Ruhmkorff coil[1] after Heinrich Rühmkorff) is a type of electrical transformer [2][3][4] used to produce high-voltage pulses from a low-voltage direct current (DC) supply. [1][5] To ...

7. Inductor - Wikipedia

   en.wikipedia.org/wiki/Inductor

   An inductor, also called a coil, choke, or reactor, is a passive two-terminal electrical component that stores energy in a magnetic field when electric current flows through it. [1] An inductor typically consists of an insulated wire wound into a coil. When the current flowing through the coil changes, the time-varying magnetic field induces an ...
