  2. Ayrton shunt - Wikipedia

    en.wikipedia.org/wiki/Ayrton_shunt

    Ayrton shunt switching principle. The Ayrton shunt or universal shunt is a high-resistance shunt used in galvanometers to increase their range [1] without changing the damping. [2] The circuit is named after its inventor William E. Ayrton. [3] Multirange ammeters that use this technique are more accurate than those using a make-before-break ...

  3. Shunt (electrical) - Wikipedia

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

    A shunt is a device that is designed to provide a low-resistance path for an electrical current in a circuit. It is typically used to divert current away from a system or component in order to prevent overcurrent. Electrical shunts are commonly used in a variety of applications including power distribution systems, electrical measurement ...

  4. Ammeter - Wikipedia

    en.wikipedia.org/wiki/Ammeter

    Ayrton shunt switching principle To make a multi-range ammeter, a selector switch can be used to connect one of a number of shunts across the meter. It must be a make-before-break switch to avoid damaging current surges through the meter movement when switching ranges.

  5. Ayrton–Perry winding - Wikipedia

    en.wikipedia.org/wiki/Ayrton–Perry_winding

    An Ayrton–Perry winding (named for William Edward Ayrton and John Perry) is a type of bifilar winding pattern used in winding wire on forms to make RF resistors. Its advantage is that the resulting coil of wire has low values of parasitic inductance and parasitic capacitance . [ 1 ]

  6. Bifilar coil - Wikipedia

    en.wikipedia.org/wiki/Bifilar_coil

    German physicist Wilhelm Eduard Weber made use of the bifilar coil in his 1848 electrodynamometer. [3] Large examples were used in inventor Daniel McFarland Cook's 1871 "Electro-Magnetic Battery" [4] and Nikola Tesla's high frequency power experiments at the end of the 1800s. [5]

  7. Theory of solar cells - Wikipedia

    en.wikipedia.org/wiki/Theory_of_solar_cells

    As shunt resistance decreases, the current diverted through the shunt resistor increases for a given level of junction voltage. The result is that the voltage-controlled portion of the I-V curve begins to sag far from the origin, producing a significant decrease in I out {\displaystyle I_{\text{out}}} and a slight reduction in V OC .

  8. Manganin - Wikipedia

    en.wikipedia.org/wiki/Manganin

    Manganin foil and wire is used in the manufacture of resistors, particularly ammeter shunts, because of its virtually zero temperature coefficient of resistance value [2] and long term stability. Several Manganin resistors served as the legal standard for the ohm in the United States from 1901 to 1990. [ 3 ]

  9. Heterojunction solar cell - Wikipedia

    en.wikipedia.org/wiki/Heterojunction_solar_cell

    To achieve a fill factor over 86%, a high efficiency heterojunction cell must have a very high shunt resistance, a negligible series resistance, high quality bulk silicon with very long minority carrier lifetime (~15 ms), excellent passivation (saturation current density below 0.8 fA/cm 2).
