A galvanometer acting as a voltmeter will have

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

Text Solution

Verified by Experts

The correct Answer is:
B
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 sereis with the galvanometre as shown in the figure. The value of this resistance to be connected depends on the range of the voltmeter.
