In the circuit diagram given below AB is a uni form wire of resistance 15 ohm and length one metre It is connected to a series arrangement of cell of emf 2 0 V and negligible internal resis tance and a resistor R Terminal A is also con nected to an electrochemical cell 2 of emf 75 mV and a galvanometer G In this set up a balancing point is obtained at 30 cm mark from A Calculate the resistance of R If 5 were to have an emf of 300 mV where will you expect the balancing point to be V XAB PAB PAR N ta RAB 15 LAB Im A E wi R www B
