A galvanometer of resistance G can be converted into a voltmeter of range `theta-V` volts by connecting a resistance R in series with it. How much resistance will be required to change its range from 0 to `V//2`?

A galvanmeter of resistance G is converted into a voltmeter of range 0 -1V by connecting resistance R_1 in series with it. The additional resistance that should be connected in series with R_1 to increase the range of the voltmeter to 0-2 V will be :

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 0-25 m A ammeter having resistance 10 Omega is to be converted into voltmeter with a range 0-25 V. A resistance connected in series is
