  2. Ayrton shunt - Wikipedia

    en.wikipedia.org/wiki/Ayrton_shunt

    The selector switch changes the amount of resistance in parallel with R m (meter resistance). The voltage drop across parallel branches is always equal. When all resistances are placed in parallel with R m maximum sensitivity of ammeter is reached. [5] Ayrton shunt is rarely used for currents above 10 amperes. [6] m1 = I1/Im , m2 = I2/Im, m3 ...

  3. Shunt (electrical) - Wikipedia

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

    An ammeter shunt allows the measurement of current values too large to be directly measured by a particular ammeter. In this case, a separate shunt, a resistor of very low but accurately known resistance, is placed in parallel with a voltmeter, so that virtually all of the current to be measured will flow through the shunt (provided that the ...

  4. Ammeter - Wikipedia

    en.wikipedia.org/wiki/Ammeter

    Traditionally, the meter used with a shunt has a full-scale deflection (FSD) of 50 mV, so shunts are typically designed to produce a voltage drop of 50 mV when carrying their full rated current. 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.

  5. Resistor - Wikipedia

    en.wikipedia.org/wiki/Resistor

    An ammeter shunt is a special type of current-sensing resistor, having four terminals and a value in milliohms or even micro-ohms. Current-measuring instruments, by themselves, can usually accept only limited currents. To measure high currents, the current passes through the shunt across which the voltage drop is measured and interpreted as ...

    Also called chordal or DC resistance This corresponds to the usual definition of resistance; the voltage divided by the current R s t a t i c = V I. {\displaystyle R_{\mathrm {static} }={V \over I}.} It is the slope of the line (chord) from the origin through the point on the curve. Static resistance determines the power dissipation in an electrical component. Points on the current–voltage ...
