Question

when terminals of cells are connected by a wire of resis†an ce 4 ohm,the p.d of the cell is 1.6V .If a second wire of same resis†an ce is connected in parallel with the first, the p.dbecomes 1.33V What will be the p.d when a third wire of same resis†an ce is connected in parallel with theother two.?Also find the emf and internal resis†an ce of
