Two known ratio arms of a Wheatstone bridge are 4000 and 400 2. The bridge is to be used to measure a resistance of 100 2. Two galvanometers are available: one with a resistance of 50 Q and a sensitivity of 0.05 μA/mm, and one with a resistance of 500 2 and a sensitivity of 0.2 µA/mm. Which galvanometer would you prefer to use? Assume that the galvanometer is connected from the junction of the ratio arms to the opposite corner of the bridge.
