A moving coil galvanometer allows a full scale current of 10–4 A. A series resistance of 2 MΩ is required to convert the above galvanometer into a voltmeter of range 0-5 V. Therefore the value of shunt resistance required to convert the above galvanometer into an ammeter of range 0-10 mA is :
(1) 10Ω (2) 500Ω (3) 100Ω (4) 200Ω
