What is the battery in a working circuit?
Source
What connects the source and a load in a working circuit?
Wire
What is an example of a load in a working circuit?
light bulb or propeller
What happens to the light bulb if you break a circuit?
It goes out.
What is the job of a switch in a working circuit?
It completes or opens a circuit. Stops or allows the flow of electricity.
What is a buildup of electrical charges?
Static Electricity
A device that opens or closes a circuit.
Switch
Materials that do not allow electricity to flow through easily.
Insulators
Materials that allow electricity to flow easily.
Conductors
What type of insulator covers wires to protect against shocks?
plastic or rubber
Tiny particles in matter that carry little bits of electricity.
The path is open (broken) in a circuit and not working.
Open Circuit
The path is closed (complete) or working in a circuit.
Closed Circuit
Circuit
Is aluminum a good conductor or insulator?
Conductor
What is it called when static electric charges jump off a charged object?
electric discharge
A circuit that only has one path for the charges to follow.
Series Circuit
A circuit that has more than one path for the charges to follow.
Parallel Circuit
A device that protects homes by opening an overloaded circuit that is overheated and could cause a fire.
fuse
Is a plastic straw a good conductor or insulator?
