Shunts and multipliers

WebFor Shunt: I Rshunt=Rm FSD whence: Rshunt= IRm FSD For Mutiplier: FSD (Rmult+Rm)=V and so: Rmult=(VFSD)−Rm Where: FSD = Meter Full Scale Deflection I = Current Range V = Voltage Range Rshunt = Shunt Resistance WebThis equation is specific to the voltage (V) across the resistance (R in ohms) being generated as a result of the resistance and current (I in amps) circulating through the resistance. As an example, a current shunt with resistance of 0.002 ohms and current of 30 Amps will result in the generation of 0.002 x 30 = 0.06 volts or 60 mV (milliVolts).

WebMar 20, 2024 · A large portion of the current being measured will then flow through the shunt. A voltmeter can be converted from a meter of small full-scale-deflection voltage by connecting a large resistor in series with it. This large resistor is known as a multiplier. A large portion of the voltage being measured will then drop across the multiplier.

Amp meters can be used to measure different current ranges, to do this the meter must have a shunt resistor fitted in parallel with the measuring circuit. Where Rs is the shunt resistor, Rm is the meters internal resistance and n is the multiplier (Current to be Measured).

WebApr 26, 2024 · The range of an ammeter can be extended by using a shunt. Hence, by adding a number of shunts, it can be used as a multirange ammeter and such arrangement is … One example is in miniature Christmas lights which are wired in series. When the filament burns out in one of the incandescent light bulbs, the full line voltage appears across the burnt out bulb. A shunt resistor, which has been connected in parallel across the filament before it burnt out, will then short out to bypass the burnt filament and allow the rest of the string to light. If too many lights burn out however, a shunt will also burn out, requiring the use of a multimeter to find the po…
