A thin uniform wire 50 cm long and of 1 S resistance is connected to the terminals of an accumulator of emf 2.2 V and the internal resistance 0.1 S (Fig. 12.17). If the terminals of another cell can be connected to two points 26 cm apart on the wire without altering the current in the wire, what is the emf of the cell?

Solution:
A thin uniform wire 50 cm long and of 1 S resistance is connected to the termina
