Current Electricity

A student is provided with a variable voltage source \(\mathrm{V}\), a test resistor \(R_{T}=10 ~\Omega\), two identical galvanometers \(G_{1}\) and \(G_{2}\) and two additional resistors, \(R_{1}=10 ~M \Omega\) and \(R_{2}=0.001 ~\Omega\). For conducting an experiment to verify ohm's law, the most suitable circuit is:
