A galvanometer can be converted into a voltmeter of certain range by connecting a resistance of `880Omega` in series with it. When the resistance of `420Omega` is connected in series, the range becomes half. Find the resistance of galvanometer.

(a) Briefly explain how a galvanometer is converted into a voltmeter. (b) A voltmeter of a certain range is constructed by connecting a resistance of 980 Omega in series with a galvanometer. When the resistance of 470 Omega is connected in series, the range gets halved. Find the resistance of the galvanometer.

(a) Briefly explain how a galvanometer is converted into a voltmeter. (b) A voltmeter of a certain range is constructed by connecting a resistance of 90 Omega in series with a galvanometer. When the resistance of 470 Omega is connected in series, the range gets halved. Find the resistance of the galvanometer.
