Special Sub-Topic: True, False, Yes, or No: Circuits
|First an easy one- Will a lightbulb that is part of a complete circuit light up? |
y. Complete circuits light when everything is attached, and there are no breaks.
|An open circuit is a type of circuit. True or false?|
t. Some more types of circuits are: short, control, power, branch, dedicated, feeder, and transmission circuits.
|A series circuit has one path from the source and back to the source again. True or false?|
t. An example of the series circuit is a string of Christmas lights. If you break the circuit's path at any point, it is not a complete circuit and all the lights will stop working.
|A parallel circuit has one path to the source and back to the source. True or false?|
f. In a parallel circuit each light has its own path, and there are always more than two. The removal of one of the bulbs doesn't affect any of the other bulbs at all.
|In a series circuit, the already existing lightbulb dims when another light bulb is added. True or false?|
t. The voltage drops in series circuits to distribute the power evenly between all the light bulbs. Parallel circuits are the opposite. Since each light bulb has its own path, the light bulbs do not need to share all the voltage between them, like with series circuits.
|Will a broken circuit light up?|
n. Broken circuits are the complete opposite of complete circuits.
|If you took out one bulb on a series circuit, the rest of the bulbs will keep shining. Yes or no?|
n. When you take out a light bulb on a series circuit, you are breaking the circuit. Everything needs to be connected, and by taking out that light bulb, you are breaking the chain.
|If you unscrew one of the light bulbs in a parallel circuit, the rest will stop lighting. True or false?|
f. Since each light bulb (or dry cell) has its own individual path, the rest will not be affected by one light bulb.
|Impure graphite is a conductor of electricity.|
t. Some other conductors are metals, water, and the human body. Conductors are the opposite of insulators.
|Glass is a conductor of electricity. True or false?|
f. Glass is an insulator of electricity. Some other insulators are: plastics, styrofoam, paper, rubber, and dry air. Insulators are the opposites of conductors.
