When an electric cell drives current through load resistance, its Back emf,
When a resistor of 11Omega is conntected in series with an electric cell, the current flwoing in it is 0.5 A. Instead, when a resistor of 5Omega is conntected to the same electric cell in series, the current increase by 0.4 A , The internal resistance of the cell is
