For my science electrical house project, me and my group decided to build a house with four rooms, a kitchen, a living room and a hall way. In the third and fourth pictures shows a outline of our house and where the lights are located. The little boxes which are filled in are the bulbs. In the first picture is our series circuit for the second bedroom(on the other side of the master bedroom). I made it to be a series circuit with two batteries connected together because i wanted to make this bulb the brightest out of the whole house. Because i cant not change the voltage of the batteries nor the lights, i decided to double the voltage to make it have more power and current flowing through the circuit . I made this circuit having one bulb because having a parallel requires more than one bulb with the same brightness. And having a series circuit with two bulbs makes them share the current and making both not as bright. With only one bulb in a double battery circuit, it makes it very bright. The dog’s room is shown in the second picture, i also used a series circuit for that room, making it bright but not as the same as the brightest. However it will be around the same as the parallel one’s brightness because the bulb is by itself and isnt sharing any current with another bulb. In the fifth picture, it shows the circuit in my living room and kitchen. I used a parallel circuit to make all four lights have the same brightness. In the last picture, it shows our bathroom, master bedroom and the hall way with a parallel circuit making all of them the same brightness. In the two parallel circuits, i chose to use them in the bigger and more important areas of the house because if one bulb burnt out, it does not affect the other bulbs. However, if the circuits were all series, it would stop all the lights after the one which is burnt out. Which is very inconvenient for a house we live in.
