NEET 2002 Physics question

To convert a galvanometer into a voltmeter one should connect a :

(1)High resistance in series with galvanometerCorrect
(2)Low resistance in series with galvanometer
(3)High resistance in parallel with galvanometer
(4)Low resistance in parallel with galvanometer

Answer: (1)

Solution

A voltmeter is connected in parallel across the component whose p.d. is measured and must draw very little current, so it must have a very large resistance. A galvanometer is converted into a voltmeter by connecting a high resistance
