3 In the given circuit AB is a uniform wire of 10 ohm and length 1 m It is connected in series with a cell E of emf 2 V and negligible internal resistance and a resistance R Terminal A is also connected to a cell E of emf 100 mV and a galvanometer G In this set up a balance point is obtained at 40 cm mark from A Calculate the resistance R If E were to have an emf of 300 mV where will you expect the balancing point to be E A E R R 102 G B
