Sahay Sir > Question Answers > Figure shows a potentiometer circuit for determining the mal resistance of a cell. when switch S is opened
A potentiometer wire of length L and resistance Ro. it is connected to a battery and a resistancev comination as shown in fig. obtain an expression for potential drop per unit length of this potentiometer wire. what is the maximyum emf of the “test cell” for which one can get a “balance point” on this potentiometer wire? what precaution should one take while combining this “test cell” in the circuit?

the balance point is found to be at 76.3 cm of the wire. when switch S is closed and the value of R is 4 ohm ,
the balance points shifts to 60 cm. find the internal resistance of cell C". ,
