A galvanometer of resistance G is converted into a voltameter of range 0 - 1   V by connecting a resistance R 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 :

Question

A galvanometer of resistance G is converted into a voltameter of range 0 - 1 &#160; V by connecting a resistance R 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 :

Aicharya · Accepted Answer

i g R 1 + G = 1 i g R 1 + G + R 2 = 2 1 R 1 + G R 1 + G + R 2 = 2 R 1 + G + R 2 = 2 R 1 + 2 G R 2 = R 1 + G
