    Cells and batteries

    Cells and batteries convert chemical energy to electrical energy. They are used to provide power to portable electronic equipment. They may also be used for backup power in the event of a power failure.

    The single cells shown in Figure 24 can produce 1 to 4 volts, depending on their compositions. For example, cells may be carbon zinc, alkaline manganese, nickel cadmium, silver oxide or lithium types.
