In this topic, you study the Multi Range Ammeters or Universal Shunt.
The current range of ammeters can be further extended by using a number of shunts and selected the required one by a range switch. The ammeter using this type of shunt (called universal shunt) is known as multi range ammeter. This shunt is used in multimeters – the single instrument, which can read currents, voltage and resistance (Fig. 1).
