(a) Six lead-acid type of secondary cells each of emf `2.0 V` and internal resistacne `0.015Omega` are joined in series to provide a supply to a resistance of `8.5 Omega.` What are the current drawn from the suply and its terminal voltage ?
(b) A secondary cell 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 tghe starting motor of a car ?
