It is required to measure the resistance of a circuit operating at 120 V. There is only one galvanometer of current sensitivity 10^−6 A per division. How should the galvanometer be connected in the circuit to operate an ohmmeter? Why minimum resistance can be measured with such a galvanometer if its full-scale has 40 divisions?
