In the given circuit AB is a uniform wire of 102 and length 1 m It is connected to series arrangement R 100 O G B of cell of e m f 2 V and negligible internal resistance and a resistor R Terminal A is also connected to an electrochemical cell e of em f 100 mV and a galvanometer G In this set up a balancing point is obtained at 40 cm mark from A Calculate the resistance R If 2 were to have an c m f of 300 mV where will you expect the CRSE
