Problem
A galvanometer having a coil resistance of 100Ω gives a full scale deflection, when a current of 1 mA is passed through it. The value of the resistance, which can convert this galvanometer into an ammeter giving a full scale deflection for a current of 10 A, is :
(1) 0.1Ω
(2) 3Ω
(3) 0.01Ω
(4) 2Ω
