$State the principle of working of a galvanometerA galvanometer of resistance G is converted into a voltmeter to measure upto V volts by connecting a resistance R_{1} in series with the coil. If a resistance R_{2} is connected in series with it then it can measure upto V/2 volts. Find the resistance, in terms of R_{1} and R_{2}, required to be connected to convert it into a voltmeter that can read upto 2 V. Also the resistance G of the galvanometer in terms of R_{1} and R_{2}$
