Six lead-acid type of secondary cells each of emf 2.0 V and internal resistance 0.015 are joined in series to provide a supply to a resistance of 8.5 Q. What are the current drawn from the supply and its terminal voltage? A secondary cell after long use has an emf of 1.9 V and a large internal resistance of 380 22. What maximum current can be drawn from the cell? Could the cell drive the starting motor of a car?
