Problem

A moving coil galvanometer allows a full scale current of

10^{-4}

A. A series resistance of

2 M\Omega

is required to convert the above galvanometer into a voltmeter of range

0 - 5V

. Therefore the value of shunt resistance required to convert the above galvanometer into an ammeter of range

0 - 10

mA is : (1)

500 \Omega

(2)

100 \Omega

(3)

200 \Omega

(4)

10 \Omega
