1. We know the full-scale deflection current for the galvanometer (Igalv) is 205 mA, and we want

A galvanometer has a coil resistance of Rgalv = 67.7 ?. It is to be made into an ammeter with a full-scale deflection equal to I = 1.45 A. If the galvanometer deflects full scale for a current of Igalv = 205 mA, what size shunt resistor should be used? size of shunt resistor: ?
