Electric House Project

For our science 9 final project, we were asked to build a electric house with cardboard, wires, and switches to make sure they activate. I was surprised that all our circuit works.

1. You have three lights bulbs. All have the same intensity when lit. Explain how you can prove to a classmate that they are connected in series by unscrewing one light bulb. Support your answer.

When you unscrew the lightbulbs or turn them off, the electrons have no home to go to and no circuit to complete therefore letting the electrons fall off and have to go back not lighting the rest of the lightbulbs and pushing the electrons through the full circuit.

2. You have three light bulbs. All have the same intensity when lit. Explain how you can prove to a classmate that they are connected in parallel by unscrewing one light bulb.

When the lightbulbs being in parallel, it means multiple other lightbulbs are still available to complete the circuit, and thus allowing them finish the loop by going through the other bulbs which are attached.

3.You have three light bulbs. Two are connected in parallel. This parallel combination is connected in series with the third light bulb. Describe the relative intensity of each bulb. Support your answer.

When there were 3 light bulbs connected in series, the power of each one will become equally as strong, why because there is one battery available for every light bulb. Therefore, they held no different intensity between each bulb.

4.In question number three, describe the relative intensities of the two remaining lit bulbs if one of the bulbs in parallel was unscrewed. Support your answer.

If one bulb was unscrewed both would still receive the equal charge as the battery is available for every light bulb
