Electricity
What type of material allows electricity to flow easily through it?
What are conductors?
This type of charge builds up on objects when electrons move from one surface to another.
What is static charge?
This type of material does not allow electricity to flow through it.
What is an insulator?
If this is missing from a circuit, the flow of electricity cannot occur, making the circuit open.
What is a complete path (or closed connection)?
What happens to the flow of electricity if there is an opening in a circuit?
does not flow because the circuit is open
When two objects with opposite charges come close to each other, they will do this.
What is attract?
A rubber-coated wire is an example of this type of material.
What is an insulator?
This device can be used to open or close a circuit.
What is a switch?
In a simple circuit, what are the three basic components required for it to work?
A battery, wire, and bulb.
The phenomenon where static electricity is discharged suddenly, often seen when you touch a doorknob after walking on carpet, is called this.
What is a shock? or What is a charge?
This type of circuit allows electricity to flow freely through it.
What is a closed circuit?
This material is typically used to create a pathway in a circuit and allows the flow of electrons.
What are wires or alligator clips?
How does wrapping wire around an iron nail and creating a closed circuit demonstrate electromagnetism?
The current flowing through the wire creates a magnetic field, making the iron nail act as a magnet.
This material allows electricity to flow through it easily.
What is a conductor?
This happens to an electrical circuit when it is broken or incomplete.
What is an open circuit?
When a light bulb is part of a circuit and does not light up, the circuit is most likely this.
What is an open circuit?
What four factors can affect the strength of an electromagnet?
The number of coils, the amount of current, the gauge of the wire, and the type of iron core.
This is an example of a material that is a conductor.
What is a metal?
n a closed circuit, this is the object that allows the flow of electricity through the circuit.
What is a wire?
This happens when you rub a balloon on your hair and the balloon sticks to the wall. It's an example of this type of electricity.
What is static electricity?
