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
500 Ω
2
100 Ω
3
200 Ω
4
None of the above
