A Multirange Ammeter The resistance of the moving coil of the galvanometer G in Fig. is 48.0 Ω, and the galvanometer deflects full scale with a current of 0.0200 A. When the meter is connected to the circuit being measured, one connection is made to the post marked +and the other to the post marked with the desired current range. Find the magnitudes of the resistances R1, R2, and R3 required to convert the galvanometer to a multirange ammeter deflecting full scale with currents of 10.0 A. 1.00 A. and 0.100 A.
