(a)List two major types of a cell.
(b) Two cells each with a terminal voltage of 1.5v and internal resistance of 0.1Ω are connected across a 2Ω resistor.
If the cells are connected in series.
(i) draw the equivalent circuit diagram;
(ii) calculate the voltage across the 2Ω resistor;
(iii)calculate the current from the cells.
