(1) Two resistors of resistance 4 ohm and 6 ohm are connected in parallel to a cell to draw 0.5 A current from the cell.calculate the current in each resistor.
(2) A cell supplies a current of 1.2 A through 2 ohm resistors connected in parallel.When the resistors are connected in series,it supplies a current of 0.4 A.Calculate:
(i) the internal resistance,and
(ii) the e.m.f. of the cell
