Vocabulary
What is electric current?
The continuous flow of electric charges through a material.
What is resistance?
The measure of how difficult it is for charges to flow through an object.
What affects current flow?
Current flow is affected by the energy of the charges and the properties of the objects that the charges flow through.
What is electric circuit?
A complete, unbroken path that charges can flow through.
A battery will not tell us....
Describe what happened to the LED bulb before a resistance was added to the circuit. Why did this happen?
The circuit blew. The resistance controls the flow of electric current.
What is a conductor?
A material through which charge can flow easily.
The potential energy is converted into ______ and _______ in a circuit with a light bulb.
heat and light
Which type of electric charges Do Not flow continuously?
Static electric charges
What is insulator?
Materials that do not allow charges to flow.
The energy source for the circuit we will build in class is a __________.
Battery
Opposing team's choice
:)
What is voltage?
The difference in electric potential energy per charge between two points in circuit.
Describe the significance of the cartoon we saw in the resistance video.
Scholars are able to describe what is happening in the cartoon.
How is a runner running through a city street route similar to an electric circuit? What happens if the road is blocked? What happens if the circuit is blocked?
The runner moves like a charge in a an electric circuit. If nothing stands in the way of the runner completing his or her route, he or she is continuously moving like a closed circuit. If, however, a road is closed or a tree blocks his or her path, then he or she is not able to complete the route or 'loop'. This would be an example of an open circuit.
