The ammeter as an ohmic resistor in a circuit

P3.2.4.1:
In the experiment P3.2.4.1, the internal resistance of an ammeter is determined by measuring the voltage which drops at the ammeter during current measurement. It is subsequently shown that the deflection of the ammeter pointer is reduced by half, or that the current measuring range is correspondingly doubled, by connecting a second resistor equal to the internal resistance in parallel to the ammeter.
