357303 Figure shows a potentiometer circuit for measuring the internal resistance \(r\) of a cell \(Y\). When the cell is an open circuit, \(T\) is the balance point on the wire \(P Q\). The resistor \(R^{\prime}\) is used

357304 \(A B\) is a potentiometer wire of length \(100\;cm\) and its resistance is \(10\,ohm\). It is connected in series with a resistance \(R = 40\,ohm\) and a battery of \(e.m.f.\) \(2{\rm{ }}V\) and negligible internal resistance. If a source of unknown \(e.m.f.\) \(E\) is balanced by \(40\;cm\) length of the potentiometer wire, the value of \(E\) is:

357305 Statement A :
The e.m.f of the driver cell in the potentiometer experiment should be greater that the e.m.f of the cell whose emf is to be determined.
Statement B :
The potential difference across the potentiometer wire should not be less than the e.m.f of the cell to be determined
