    Answer:

    4.5V

    Explanation:

    In a arrangement of cells, the cells could be joined end to end(series) or to a common junction (parallel).

    When cells are joined in series, the total emf of the cell is the sum of the individual emf of all the cells.

    Hence;

    Total emf = 1.5V + 1.5V + 1.5 V = 4.5 Volts
