The Electric House

Circuit Requirements  The house must have at least 3 working circuits. Each circuit must function independently from the other circuit. You may include a switch or turn circuit off and on manually  Each circuit may use a maximum of 9Volts. Each circuit may have its own battery, or a common power station for both circuits is allowed if the wiring is neat enough to trace.  One circuit must be purely series and use at least two Christmas tree lamps, one circuit must be purely parallel and use at least two Christmas tree lamps, and one circuit must be complex and use at least three Christmas tree lamps. House Requirements  The house must have at least four rooms and two floors. Each room must have at least one bulb to illuminate it when turned on.  The house must have a front door and porch light. The porch light may be part of any of circuit.  The maximum allowed length in any dimension is 40 cm. The base the house sits on, and the roof are included in the 40 cm dimensions. For example, if you want a 10 cm front yard, then the house can only be 30 cm deep. Materials you will need . At least eight Christmas tree lamps. Your teacher may have pieces of Christmas light strings available if you cannot find them elsewhere. . At least one battery. Remember, no circuit may use more than 9 volts at any time. . Wire. The extra wire from the Christmas tree lights works well. Your teacher may have pieces wire if you cannot find it elsewhere. . Shoeboxes, Foam-core project board, cardboard or some other lightweight material may be used). . Tape or glue to connect the walls. Items to decorate your house. . House must be disposed of properly (per teacher’s instructions). Failure to do so can result in a 10 point deduction.
