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:

A series circuit is a circuit where electrons only have one path to travel in. This means that if one light is broken or unscrewed, the electrons reach a dead end. This dead end makes it so that the electrons can’t come back to the battery which leads to a defective circuit. In this case, if one of three light bulbs is unscrewed, the rest of the light bulbs will not light up. This proves that the electrons only have one path which means that the circuit is a series.

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:

A parallel circuit is a circuit where electrons have multiple paths to travel. Electrons divide into multiple paths to power their loads. This means that if a path is obstructed(the load is broken or removed) the electrons will still be able to pass through a different path and power a different load. I can prove that a circuit is parallel by unscrewing a light bulb. If the other 2 light bulbs stay on, the circuit is a parallel.

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:

This type of circuit is called a complex circuit. It is a mix of series and parallel. The electrons flow through the series path which leads to a parallel path. When the electrons get to the parallel path, the amount of electrons divide into the parallel circuit. This means that the series light would be significantly more lit than the parallel lights. The series light would be receiving more electrons than the parallel lights because the electrons were not divided into multiple paths.

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 there are only 2 parallel lights in the complex circuit, once one of the parallel lights are removed, the circuit will act like a series. The electrons will only have one path because the other paths reach a dead end. Both lights would have the same intensity because they’re receiving the same amount of electrons.
