A voltmeter is made by connecting a high resistance $R_{1}$ in series with the galvanometer $G_{1}$ .

An ammeter is made by connecting a low resistance $R_{2}$ in parallel with the galvanometer $G_{2}$ .

The voltmeter is connected in parallel with the test resistor $R_{T}$ in the circuit.

The ammeter is connected in series with the test resistor $R_{T}$ in the circuit.

A variable voltage source $V$ is connected in series with the test resistor $R_{T}$ in the circuit.
