Copper, gold, silver, and aluminum are all examples of
What is conductors
100
These can provide the energy to move electric charges through a circuit.
What are batteries or power plants
100
Don't touch these when they are in use, or cover them with safety caps
What are electrical outlets
100
Magnets that carry an electric current
What are electromagnets
200
Some particles that make up atoms (3)
What are protons, electrons, and neutrons
200
a material that slows the flow of an electric charge
What is a resistor
200
This controls the flow of charges by closing or opening a gap in the circuit
What are switches and push-buttons
200
Replace this on a frayed cord
What is an insulator, plastic, or rubber coating
200
The difference between an electromagnet and a regular magnet
What is the ability to turn the electromagnet on and off
300
Electrons were removed separated from the protons, resulting in this
What is static electricity
300
Plastic and rubber are good examples of this
What is an insulator
300
The energy of moving electric charges within a circuit
What is electrical energy
300
Do not use these near a bathtub, pool, lake, or puddle
What is a cord-operated appliance
300
Two examples of when electromagnets are useful
What is motors, doorbells, sound systems, junkyards, etc.
400
The movement of electrons
What is electricity
400
These are opposites: one allows electricity to flow easily and the others stop its flow.
What are conductors and insulators
400
A map of a circuit
What is a circuit diagram
400
An example of a parallel circuit in your home
What is power strip, Christmas lights, light fixture with more than one bulb, etc.
400
The symbol for an electromagnet
What is a curly cue
500
What happens when you insert two batteries in a flashlight so that the negative end of one battery touches the negative end of the other
What is NOTHING (the flashlight will not work because the electricity needs the negative end to connect with the positive end to flow)
500
Dry salt is a good insulator. If you stir some table salt into a glass of water, is it still a good insulator? Why or why not.
What is NO- the salt water becomes a good conductor.
500
The measure of the electrical force provided by an energy source
What is volt
500
Three things that happen when you are electrocuted.
What is 1. chest muscles contract 2. heart cannot pump blood, veins are constricted 3. burns show at the entrance and exit points 4. muscle spasms make you unable to free yourself
500
How electromagnetism was discovered
Who is Hans Christian Oersted, a Danish professor by turning on an electric current and watching the needle of a nearby compass move
