A 10 m wire potentiometer is connected to an accumulator of steady voltage. A 7.8 m length of it balances the emf of a cell on 'open-circuit'. When cell delivers current through a conductor of resistance 10Ω it is balanced against 7.0 cm of the same poleutomelic. What is the internal resistance of the cell?
