Energy
What type of energy does a lamp give off?
Light energy
What provides energy to a circuit?
Battery
How many pathways does a series circuit have?
One
Does a metal paper clip act as a conductor or insulator?
Conductor
What happens to a bulb when there is a break in the circuit?
It does not light.
What type of energy does a toaster mostly produce?
Heat energy
What must a circuit have for electricity to travel through it?
A complete/closed path
Which circuit has more than one pathway?
Parallel circuit
Does a rubber eraser act as a conductor or insulator?
Insulator
Why can a bulb light in a closed circuit?
There is a complete path for electricity to travel.
A speaker changes electrical energy mostly into what type of energy?
Sound energy
Name 3 parts that can be used to make a working circuit.
Battery, wires, bulb/device (switch can also be accepted)
One pathway stops working, but the other lights stay on. What type of circuit is this?
Parallel
What does a conductor allow electricity to do?
Flow/move through it easily
A plastic covering is placed around an electrical wire. Why?
Plastic is an insulator and helps stop electricity from flowing through it to a person.
What does it mean when we say energy can transfer from place to place?
Energy can move from one place/object to another
A battery, wires, and bulb are connected, but there is a gap between two wires. Will the bulb light? Explain.
No, because the path is incomplete/open.
Explain one difference between a series and parallel circuit.
Series has one pathway; parallel has more than one pathway.
Which would you choose to allow electricity to flow: metal or plastic?
Metal because it is a conductor.
Some lights in a strand are working while others are not. What could this tell you about the circuit?
It may be parallel because there is more than one pathway, allowing some lights to continue working.
