100
What is a conductor?
a material that allows electric current to flow through it.
100
What type of circuit do you need for electricity to flow?
A Closed Circuit
100
Wat type of energy has the electricity been transformed into when a doorbell is rang?
sound energy
100
What is the difference between an open and a closed circuit?
closed=no gaps in the path, allows energy to flow
open=there are gaps in the path and energy will not flow.
200
What is electricity?
the flow of electric charges.
200
No electricity will flow through a circuit that has an open switch.
True or False
True
200
Why do electricians wear rubber gloves?
to insulate and protect themselves.
200
True or False
No electricity will flow through a circuit without a light bulb.
FALSE.
300
What is an insulator?
a material that does not allow an electric current to flow through it.
300
What is the purpose of the switch in a circuit?
used to open or close a circuit.

Rahim is watching his favorite football team on television. In order to work, the television must be plugged into an electrical outlet. When the television gets turned on, what is the main energy transformation demonstrated by the television?
electrical energy into light energy
300
What is an electric current?
What is the flow of electric charge.
400
What is resistance?
the opposition of a material to the flow of electric current through it.
Slows down the flow of electricity
400
What is a circuit?
What is a connected set of electrical elements.
400
If a fan is powered by electricity, what type of energy is the electricity transformed into?
Mechanical
(also known as motion)
400

What are examples of Insulators?
Conductors: anything metal; steel, copper, gold, paperclip, coin
Insulators: plastic, glass, wood, rubber
500
What needs to be added to this circuit to make it work?
Add a wire from the switch's unused electrical contact to the negative terminal of the battery.
500
What type of material should a switch use to close a circuit?
The switch must use a conductive material such as copper to close the circuit and light the bulb.
500
True or False
Electricity will flow through a circuit that forms an incomplete loop.
FALSE
