Question

A galvanometer of resistance 50 Ω is converted into an ammeter by connecting a low resistance (shunt) of value 1 Ω in parallel to the galvanometer, S . If full-scale deflection current of the galvanometer is 10 m A , then the maximum current that can be measured by the ammeter is -, 500 m A, 510 m A, 610 m A, 490 m A

S = G I g I – I g Shunt and Galvnometer are in parallel combination 1 = 50 × 10 I – 10 I - 1 0 = 500 I = 510 m A
