![]() Then remove the plugs of keys K, and K2.Measure the balancing length ( L) from end P.Slide the jockey along a potentiometer wire and obtain the null point.At the same time, take out a small resistance (1-5 W) from the shunt resistance box connected in parallel with the cell. Next introduce plugs in both keys and. ![]() Determine the position of the null point accurately using a set square and measure the balancing length (1) between the null point and the end P.Without inserting a plug-in key, adjust the rheostat so that a null point is obtained on the last wire of the potentiometer.Take maximum current from the battery, making rheostat resistance small.Keep both the electrodes at a distance of 16 cm.To study variation of internal resistance with distance of separation of the battery is more than that of the cell, otherwise null or balance point will not be obtained. of the battery and of the cell and make sure that e.m.f. Tighten the plugs of the resistance box.Clean the ends of the connecting wires with sand paper and make tight connections according to the circuit diagram. ![]()
