A moving coil galvanometer allows a full scale current of A. A series resistance of 200 is required to convert the above galvanometer into an voltmeter of range0-5 V . Therefore the value of shunt resistance required to convert the above galvanometer into an ammeter of range0-10 mA is :
Conversion of galvanometer into voltameter -
Connected a large Resistance in series
- wherein
(R+G) I = V
=>
G=300
