Did you know?
WebWhat size shunt resistor should be used? The size of the shunt resister depends on the maximum current rating. It is calculated by the voltage drop at the maximum current rating. Let say a shunt resistor is designed for maximum current 100 A and voltage drop 50 mV. Typically, the voltage drop at maximum current is 50 mV, 75 mV, or 100 mV. WebA resistor having a very low value of resistance such type of resistor is called shunt resistance. The shunt resistor is mainly made of the material having a low temperature coefficient of resistance. It is connected in parallel with the ammeter whose range is to be extended. It is also connected in series with the load whose current is to be measured.
