A student is provided with a variable voltage source V, a test resistor $\displaystyle R_T=10 \Omega$, two identical galvanometers $\displaystyle G_1$ and $\displaystyle G_2$ and two additional resistors, $\displaystyle R_1=10 M \Omega$ and $\displaystyle R_2=0.001 \Omega$. For conducting an experiment to verify ohm's law, the most suitable circuit is:
