Six lead-acid type of secondary cells each of emf `2.0` V and internal resistance `0.015Omega` are jouned in series to provide a supply to a resistance of `8.5Omega`. What are the current drawn from the supply and its terminal voltage ?
(b) A secondary cells after long use has an emf of `1-9` V and a large internal resistance of `380 Omega`. What maximum current can be drawn from the cell ? Could the cell drive the starting motor of a car ?
