    My daughter has turned to me for help with her homework project for Science class and alas I'm at a total loss.

    The idea is to design a basic lighting system with the following criteria:

    -Main room has 3 lights in total- 1 light controlled by a switch & 2 lights wirted in parallel controlled by a second switch.

    Bedroom 1- has 2 lights wired in series controlled by a third switch.

    Bedroom 2- 1 light wired in parallel with 2 lights wired in series all controlled by a fourth switch

    Bathroom has 1 light controlled by a fifth switch.

    Here is the problem

    only 1 9volt battery may be used to power all,
    only 1 wire to each terminal on the battery (no junction boxes permitted, negates the idea of the project lol)
    All 5 sets of lights must be wired in parallel with one another using a minimum of wire.

    There is my dilema, any help or guidance is greatly appreciated....thank you in advance form the electrical nooblet lol..
