Circuits
What charge does an electron have?
Negative
What is a conductor?
An object that allows electricity to pass through it.
What is the difference between static and current electricity?
Static occurs in one spot, current moves through a circuit.
What are the 3 fossil fuels?
Coal, Oil and Natural Gas
Name the 3 parts of an electrical circuit
Conductor, Load, Power Source
What is an insulator?
An insulator is an object that does not allow electricity to travel through it.
Give one example of static electricity, and one example of current electricity.
Static: lightening, balloon and hair, socks and carpet, fleece pjs..
Current: lightbulb, appliances...
How is water used to create electricity?
What is the difference between a series and parallel circuit?
A series has one pathway, a parallel has multiple pathways.
Why is it important that electrical wires are covered in plastic?
The plastic acts as an insulator that prevents you from making direct contact with the electricity in the wire.
If a negatively charged lightening bolt strikes a tree, what would the charge of the tree be?
Explain how geothermal energy is used to create electricity?
We drill into the Earth to extract the heat from the Earth's core. That heat is used to heat up water, which creates steam to turn a turbine.
Give an example of when a parallel circuit should be used.

What is a resistor?
An electrical component that limits or regulates the flow of electrical current in an electronic circuit.
Name 2 examples of insulators
Answers may vary...
Plastic, glass, rubber...
