A galvanometer can be converted to a voltmeter by connecting – (1) a high resistance in parallel (2) a high resistance in series (3) a low resistance in series (4) a low resistance in parallel
(2) a high resistance in 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 con-version is made for enabling the galvanometer to measure the potential difference across any component in a circuit.
