It is required to measure the resistance ofa circuit operating at 120V. There is only one galvanometer of current sensitivity `10^(-6)` A per division. How should the galvanometer be connected in the circuit to operate as an ohmmeter? What minimum resistance can be measured with such a galvanometer if its full scale has 40 division? Construct the entire scale of such an ohmmeter in ohms per 5 division? Neglect galvanometer resistance.
