100
This is the flow of electrons that moves in an continuous loop.
What is an electric current?
100
These are materials through which an electric current can pass.
What are conductors?
100
This is the name of the crackle you hear and feel when you touch a doorknob after rubbing your feet across a carpet.
What is static electricity?
100
These are temporary magnets, NOT permanent magnets.
What are electromagnets?
100
In this type of circuit, electricity has only one path to follow.
What is a series circuit?
200
This is the pathway taken by an electric current.
What is a circuit?
200
These are materials through which an electric current CANNOT pass.
What are insulators?
200
True or False: Positive charges move from one object to another.
False. Only electrons (negative charge) move from one object to another.
200
This term means "to push away".
What is repel?
200
In this type of circuit, electricity has more than one path to follow.
What is a parallel circuit?
300
This type of circuit is a complete circuit where everything is connected and electricity can easily flow through it.
What is a closed circuit?
300
Which of these materials is a conductor: rubber, glass, air, silver?
What silver?
300
If you rub your hair on a balloon and the balloon becomes negatively charged, what charge will your hair have?
What is a positive charge?
300
This is the invisible force field around every magnet.
What is a magnetic field?
300
This is a equipment that measure how much electrical potential is in a battery.
What is a voltmeter?
400
Is a circuit open or closed if you haven't turned on the switch?
What is an open circuit?
400
Which of these materials is not a conductor: copper, aluminum, gold, or wood?
What is wood?
400
If you rub your hair on a balloon and the balloon becomes negatively charged, then it sticks to wall, what possible charges does the wall have?
What is positive and neutral?
400
True or False: A refrigerator magnet is a permanent magnet.
True
400
These are the basic materials needed to make a complete circuit.
What are a power source (battery or outlet), wires, and a light bulb?
500
This supplies current to an electrical circuit.
What is a battery?
500
What are 4 ways you can protect yourself from an electrical shock?
1. Don't put objects (other than a plug) in outlets. 2. Don't touch metal parts of a plug when you plug it in 3. Don't use frayed cords. 4. Don't pull on a cord to unplug something. 5. Don't plug too many devices into an outlet 6. Don't use appliances around water or with wet hands.
500
What causes static electricity?
When two objects rub together, negative charges leave one object and build up on the other object, making it negative. When that object touches something, ZAP, static electricity occurs when the negative charge jumps to a positive charge.
500
An electromagnet is made up of what three items?
What is nail, copper wire and a battery?
500
This is a equipment that measure the intensity of electrical current in a circuit.
What is a ammeter?
