How range of a ammeter is extended? - Answers

WebThe word 'shunt', which has various meanings that include 'divert', 'avoid', and 'divide', conventionally refers to a resistor placed in parallel with an ammeter to shunt current. To expand the measurement range of an ammeter a resistor is placed in parallel that shunts the current flow and the total current flowing to the circuit is measured. WebIf there is a requirement to measure higher voltages, the measuring range of the instrument can be increased by placing a resistance in series with the coil, such that only a known proportion of the applied voltage is measured by the meter. In this situation the added resistance is known as a shunting resistor.
