  1. A. Cells=9Volts / 1.5Volts/cell=6Cels.

    B.

    C. If one of the cells are connected backwards, it will subtract 1.5 volts from the remaining 5 batteries:

    V = (5*1.5) - 1.5 = 7.5 - 1.5 = 6 Volts.

  3. A) 6cells
    B)
    C) The voltage across will be 0, since one connected backwards, there will be no current moving across.
