100
Rubber is a what?
Rubber is an insulator.
100
What can make a break in the circuit?
A fuse can make a break in a circuit.
100
If opposite polls attract, what do similar poles do?
Repel
100

A dimmer
200
What are the building blocks to everything?
Atoms
200
Name three conductors and two insulators.
Conductors: iron,copper,silver, etc. Insulators: glass, pure water, rubber, etc.
200
The area around electric charges, where electric forces can act is a?
Electric Field
200
Where is a magnet the strongest?
In a magnetic field
200
An electric circuit with only one path for current is what kind of circuit?
A series circuit
300
When does a neutral atom became a negative atom?
When an extra electron enters the atom.
300
Explain why is there rubber around a wire.
Rubber is an insulator so they made rubber-covered wires for safety concerns and so a circuit doesn't turn into a short circuit.
300
What is an electric charge?
Electric charge is a basic property of the tiny particles that make up matter (can be positive or negative)
300
What magnet can be made by coils of current-carrying wire around an iron core?
An electromagnet
300
An electric circuit with two or more paths for current is a what type of circuit?
A parallel circuit.
400
When does a neutral atom became a positive atom?
When an electron leaves making the atom have more protons than electrons.
400
What do you add to pure water to make it an insulator?
Nothing! Pure water is already an insulator
400
What is a special outlet with a safety switch that instantly switches off in a dangerous situation to help prevent any shocking?
A GFCI Outlet
400
List five objects to avoid while using a magnet.
Computer, television, watch, radio, credit/debit card, cell phones (most electronic devices)
400
What unit is used to measure the amount of electrical energy?
A kilo-watt hour
500
If a proton and electron entered an atom while two protons and one electrons left the atom, what is the atom's charge?
Negative
500
My electrons are close together and are slow moving. What am I?
An Insulator
500
What is the difference between a watt and a volt?
A volt is used to measure how strongly the electrons in a wire are pushed while a watt is used to measure how fast energy is used.
500
