The movement of electrons creates an electric current, which produces electricity. There are two main types of electricity: static electricity and current electricity.

● How is static electricity caused?

● How is current electricity caused?

Which of the two types of electricity powers most of our appliances?

What is a conductor? Also, give multiple examples of good conductors.

What is an insulator? Also, give multiple examples of good insulators.

Resistance is a measure of how much a material opposes the flow of electric current through a material. Which type of material has a higher resistance- a conductor or an insulator?

Is a material that holds onto its electrons tightly and doesn’t allow the flow of electrons considered a conductor or an insulator?

Copper, aluminum, and gold are all metals. Are metals good conductors of electricity?

1 answer

Static electricity is caused by the accumulation of electric charge on the surface of objects, often due to friction between materials.
Current electricity is caused by the continuous flow of electrons through a conductive material, typically driven by a voltage source.
Current electricity powers most of our appliances.
A conductor is a material that allows the flow of electric current, with good examples being copper, aluminum, and gold.
An insulator is a material that resists the flow of electric current, with good examples being rubber, glass, and wood.
An insulator has a higher resistance than a conductor.
A material that holds onto its electrons tightly and doesn’t allow the flow of electrons is considered an insulator.
Yes, metals like copper, aluminum, and gold are good conductors of electricity.
