For cells in series - calculate total e.m.f by adding their individual e.m.f.s:
ε total = ε1 + ε2 + ε3 + ...
Requires all cells to be connected in same direction - one is connected in opposite direction - subtract its e.m.f.
For identical cells in parallel - total e.m.d of combination of cells is the same size:
ε total = ε1 = ε2 = ε3 ...
