Question
Write the important points for series connection of cells.
✓
Answer
→When the current leaves each cell from the positive terminal then :
(1) The equivalent emf of a series combination of $n$ cells is just the sum of their individual emfs.
(2) The equivalent internal resistance of a series combination of $n$ cells is just the sum of their individual internal resistances.
(3) In this type of combination, if the current leaves the cell from negative terminal then to obtain equivalent emf, the emf of that cell is taken negative.
