3 18 The resistance Re of the coil of a pivoted coil galvanometer is 9 3652 and a current of 0 0224 A causes it to deflected full scale We want to convert this galvanometer to an ammeter reading 20 0 A full scale The only shunt available has a resistance of 0 025002 What resistance R must be connected in series with the coil of galvanometer RG R B
