NEET Physics Current Electricity Questions Solved

A multirange voltmeter can be constructed by using a galvanometer circuit as shown in the figure. We want to contruct a volemeter that can measure 2V, 20V and 200V using a galvanometer of resistance 10Ω and that produces maximum deflection for current of 1mA. Find the value of R1, R2 and R3 that have to be used.
