What is current electricity?
A steady stream of charges.
100
What is static electricity?
Electricity at rest.
100
In a parallel circuit, does a charge move along 1 path or 2?
2

Why should you not touch a wire to your bare skin?
Because it could kill you.
100
What is a switch?
A device that opens or closes a circuit.
200
What is more useful than static electricity?
Current electricity.
200
What causes lightning?
Static electricity.
200
What happens when you unscrew a lightbulb from a series circuit?
The circuit breaks.
200
Is it safe or unsafe to touch an electrical cord?
Safe, because it's a coated wire.
200
When you switch something on, do you open or close a circuit?
Close.
300
What produces a flow of charges?
A power plant.
300
What kind of a charge has the same number of postive and negative charges?
A neutral charge.
300
Are the lights in the school on a parallel or series circuit?
Parallel.
300
What are 4 negative effects of elecricity?
Shock, burns, injury and/or death.
300
What needs to be in between the two conductors in order for a switch to open a circuit?
An insulator.
400
True or False: current electricity moves through objects such as copper?
True.
400
How long does static electricity stay on an object?
Until something happens to remove it, such as something else touches it.
400
What kind of a circuit is in a flashlight?
A series circuit.
400
Are plastic and rubber good insulators?
Yes.
400
These are two ways in which a switch might appear.
As a lever or a button.
500
What is the path called that current electricity flows through?
A circuit.
500
How do clouds gain negative charges?
When ice crystals rub together during a storm.
500
What are the 2 types of circuits?
Parallel and series circuits.
500
Would a plastic band around a lightbulb encourage or discourage electricity to flow through it?
Discourage. It's an insulator.
500
