  2. Thermal cutoff - Wikipedia

    en.wikipedia.org/wiki/Thermal_cutoff

    A thermal cutoff is an electrical safety device (either a thermal fuse or thermal switch) that interrupts electric current when heated to a specific temperature. These devices may be for one-time use (a thermal fuse), or may be reset manually or automatically (a thermal switch).

  3. Johnson–Nyquist noise - Wikipedia

    en.wikipedia.org/wiki/Johnson–Nyquist_noise

    Johnson–Nyquist noise (thermal noise, Johnson noise, or Nyquist noise) is the electronic noise generated by the thermal agitation of the charge carriers (usually the electrons) inside an electrical conductor at equilibrium, which happens regardless of any applied voltage.

  4. Cut-off low - Wikipedia

    en.wikipedia.org/wiki/Cut-off_low

    Kona Low over Hawaii, an example of a cut-off low from the main core of the jet stream. [1]A cut-off low (or cutoff low), sometimes referred to as the weatherman's woe, is defined by the National Weather Service as "a closed upper-level low which has become completely displaced (cut off) from basic westerly current, and moves independently of that current."

  5. Cut-off (electronics) - Wikipedia

    en.wikipedia.org/wiki/Cut-off_(electronics)

    In electronics, cut-off is a state of negligible conduction that is a property of several types of electronic components when a control parameter (that usually is a well-defined voltage or electric current, but could also be an incident light intensity or a magnetic field), is lowered or increased past a value (the conduction threshold).

  6. Cutoff - Wikipedia

    en.wikipedia.org/wiki/Cutoff

    Fuse (electrical) (or cutoff), a type of overcurrent protection device. Meander cutoff, a course change in a meandering river. Cutoff functions, a construction used to eliminate singularities of a given function. Thermal cutoff, an electrical safety device that interrupts electric current when heated to a specific temperature.

  7. Fuse (electrical) - Wikipedia

    en.wikipedia.org/wiki/Fuse_(electrical)

    In electronics and electrical engineering, a fuse is an electrical safety device that operates to provide overcurrent protection of an electrical circuit. Its essential component is a metal wire or strip that melts when too much current flows through it, thereby stopping or interrupting the current.

  8. Diesel cycle - Wikipedia

    en.wikipedia.org/wiki/Diesel_cycle

    The maximum thermal efficiency of a Diesel cycle is dependent on the compression ratio and the cut-off ratio. It has the following formula under cold air standard analysis: η t h = 1 − 1 r γ − 1 ( α γ − 1 γ ( α − 1 ) ) {\displaystyle \eta _{th}=1-{\frac {1}{r^{\gamma -1}}}\left({\frac {\alpha ^{\gamma }-1}{\gamma (\alpha -1)}}\right)}

  9. Resettable fuse - Wikipedia

    en.wikipedia.org/wiki/Resettable_fuse

    Resettable fuses - PolySwitch devices. A resettable fuse or polymeric positive temperature coefficient device (PPTC) is a passive electronic component used to protect against overcurrent faults in electronic circuits.
