State the Principle of the Working of a Moving Coil Galvanometer, Giving Its Labeled Diagram ? - Physics | Shaalaa.com

State the principle of working of a galvanometerA galvanometer of resistance G is converted into a voltmeter to measure upto V volts by connecting a resistance R1 in series with the coil. If a resistance R2 is connected in series with it then it can measure upto V/2 volts. Find the resistance, in terms of R1 and R2 , required to be connected to convert it into a voltmeter that can read upto 2 V . Also find the resistance G of the galvanometer in terms of R1 and R2
