(C) To verify Ohm's law,we need to measure the potential difference across the resistor $R_T$ and the current flowing through it.$1$. $A$ voltmeter is connected in parallel to the resistor. $A$ voltmeter is formed by connecting a high resistance in series with a galvanometer. Thus,$G_1$ in series with $R_1$ connected in parallel to $R_T$ acts as a voltmeter.$2$. An ammeter is connected in series with the resistor. An ammeter is formed by connecting a small resistance (shunt) in parallel with a galvanometer. Thus,$G_2$ in parallel with $R_2$ connected in series with $R_T$ acts as an ammeter.$3$. Comparing this with the given options,option $C$ shows $G_1$ in series with $R_1$ (voltmeter) across $R_T$ and $G_2$ in parallel with $R_2$ (ammeter) in series with $R_T$.

To verify Ohm's law,a student is provided with a test resistor $R_T$,a high resistance $R_1$,a small resistance $R_2$,two identical galvanometers $G_1$ and $G_2$,and a variable voltage source $V$. The correct circuit to carry out the experiment is
