Question

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

Answer 1

sorry i am not able to understand the question
