Which arrangement of four identical resistances should be sued to draw maximum energy from cell of voltage V

(a) Six lead acid type of secondary cells each of 2.0 V and internal resistance 0.015 omega are joined in series to provide a supply resistance of 8.5 omega what are the current drawn from the supply and its terminal voltage (b) A secondary cell after long use has an e.m of 1.9 V and largic internal resistance of 380 omega what maximum current can be draw from the cell ? Could the cell drive the starting motor of a car ?
