Electricity Vocab
A continuous flow of negative charges through a material.
What is current electricity?
An electric current flowing through a wire wrapped around a piece of metal and forming a temporary magnet.
What is an electromagnet?
*Pick up spilled pins or nails
*hold screws in place on the top of a screwdriver
*identify paper money (real vs. fake)
*hear sound in speakers on computers, TV, or a car
*help a cow stay healthy (a source of food for us)
How can magnets be helpful?
Objects with the same kind of electrical charge attract.
What is false?
The correct answer is repel.
In this kind of electricity, the negative charges have a continuous flow through a material.
What is current electricity?
An unbroken path by which electricity flows.
What is a closed circuit?
An electromagnet can be made stronger by increasing the amount of this flowing through a wire.
What is an electric current?
Learning about conductors and current electricity helps keep people safe. We were made in God's image, so it pleases Him when we stay safe and healthy. Our bodies are conductors. Knowing this will help us stay safe around electricity.
Why is it important for people to know about conductors and current electricity?
Decreasing the electric current flowing through the electromagnet's wire will make the electromagnet stronger.
What is false?
The correct answer is increasing.
In this kind of electricity, electric charges build up on the surface of an object.
What is static electricity?
Objects with opposite charges do this.
What is attract?
The area around a magnet where the force of the magnet can act.
What is the magnetic field?
If the lightbulb is ON, then that means it is using this kind of circuit.
What is a closed circuit?
Electricity flows easily through conductors.
What is true?
An orange with 3 negative charges and 5 positive charges is said to have this kind of charge.
What is a positive charge?
This form of energy involves the flow of electric charges.
What is electricity?
an object that attracts certain metals.
What is a magnet?
The fan is off. That means we can call the circuit this.
What is an open circuit?
All matter is made of tiny particles called circuits.
What is false?
(The correct answer is atoms)
A brush with 8 positive and 8 negative charges is said to have this kind of charge.
What is a neutral?
Material that allows electricity to flow through it easily.
What is a conductor?
The magnet's magnetism is strongest here.
What are the poles?
The magnetism of this is temporary because it has a switch that can turn the electric current off and on.
What is an electromagnet?
You can view a magnet's magnetic field by sprinkling glitter around the magnet.
What is false?
The correct answer would be iron filings.
A dishtowel with 3 positive and 8 negative charges is said to have this kind of charge.
What is a negative charge?
