In a potentiometer circuit cell of emf 1.5
WebAnother possible way is to increase the potential droop across the potentiometer wire by increasing the voltage of driver cell. Example: The Fig. shows a 2.0 V potentiometer used for the determination of internal resistance of a 1.5 V cell. The balance point of the cell in open circuit is 76.3 cm. WebQ.11 In a potentiometer arrangement. E1 is the cell establishing current in primary circuit. E2 is the cell to be measured. AB is the potentiometer wire and G is a galvanometer. Which of the following are the essential condition for balance to be obtained. (A) The emf of E1 must be greater than the emf of E2.
