A galvanometer can be converted into a voltmeter by connecting with it a – (1) high resistance in parallel (2) low resistance on parallel (3) high resistance on series (4) low resistance in series
(3) high resistance on series Explanation: In order to convert a Galvanometer into voltmeter, a very high resistance known as "series resistance" is connected in series with the galvanometer. The conversion is made for enabling the galvanometer to measure the potential difference across any component in a circuit.
