1. The schematic illustrates a conventional ammeter shunt circuit configuration. This is the basic principle behind the operation of the meter. Of course, modern ammeter shunts are a bit more complex.

The diagram shows a 6 Ω resistor in series with a 2 Ω resistor. The total resistance for these resistors in series is 6 Ω + 2 Ω = 8 Ω. Resistors in series What is the resistance of this circuit?

Potential difference is measured using a device called a voltmeter . Just like ammeters, some types have a pointer on a dial, but most have a digital display. However, unlike an ammeter, you must ...
