What is a conductor?
What is a material that allows electric current to flow through it.
100
What is a series circuit?
What is a circuit in which there is only one path for the flow of electric current.
100
What is an incandescent light bulb?
What is a bulb that glows as a result of electric current flowing through the filament.
100
What is resistance?
What is the opposition of a material to the flow of electric current through it.
100
What is a battery terminal?
What is the negative or positive ends on a battery.
200
What is electricity?
What is the flow of electric charges.
200
What is a parallel circuit?
What is a circuit in which there is more than one path for the flow of electric current.
200
What is filament?
What is the coiled piece of wire inside a bulb that glows when electric current passes through it.
200
What happens to a light bulb as you add more batteries to it?
What is it will get brighter.
200
What is a volt?
What is the unit by which the strength of a battery is measured.
300
What is an insulator?
What is a material that does not allow an electric current to flow through it.
300
What is the purpose of the switch in a circuit?
What is a mechanical device used to open or close a circuit.
300
What is tungsten?
What is the metal used to make the filament in an incandescent bulb.
300
What is a fuse?
What is a circuit safety device containing a thin wire designed to melt and break when too much current passes through it.
300
What is an electric current?
What is the flow of electric charge.
400
What is resistance?
What is the opposition of a material to the flow of electric current through it.
400
What is a circuit?
What is a connected set of electrical elements.
400
What is a fluorescent bulb?
What is a bulb that gives off light as a result of electric current entering a tube and reacting with gases inside the tube, causing them to glow.
400
What is a difference between a switch and a fuse?
What is a switch can open and close the circuit repeatedly where as a fuse needs to be replaced after it melts.
400
How can you make a light bulb glow brigher?
What is add more batteries to it
500
What is Nichrome wire?
What is a nickel and chromium wire that is highly resistant to current and able to withstand high temperatures.
500
What is a circuit diagram?
What is a drawing of a circuit using standardized symbols.
500
Why is the filament sealed inside a glass shell?
What is if oxygen were to tough a very hot wire, it would cause the wire to burn and break.
500
Why do some wires get hot?
What is more friction is created inside high resistance wires therefor producing heat.
500
How does a battery create electricity?
What is the chemicals inside react together causing electrons to move.
