If cells are placed in series in the same direction the e.m.f. of the circuit will be the sum of the individual e.m.f.s.If the cells are not placed in the same direction the total e.m.f. will be the sum of the individual values taking the direction into account.In a series circuit the total potential difference across all the components will be the sum of their individual potential differences and this will add up to the e.m.f.
