A) a high resistance in parallel with its coil
B) a high resistance in series with its coil
C) a low resistance in parallel with its coil
D) a low resistance in series with its coil
Correct Answer: B
Solution :
Key Idea: To work as voltmeter, the resistance of galvanometer should be high. A voltmeter indeed is a modified form of a pivoted coil galvanometer. Since, the resistance of coil of galvanometer of its own is low, hence to convert a galvanometer into a. voltmeter, its resistance is to be increased. For this an appropriate high resistance is joined in series with the galvanometer as shown in figureYou need to login to perform this action.
