Study Notes

Electricity Explained

Electricity is a form of energy that enables movement and work.
All matter is composed of protons, neutrons, and electrons.
Electricity is created when electrons move.

Generating Static Electricity

Friction between objects can cause electrons to move, creating static electricity.
Rubbing materials together, such as a balloon and hair, creates friction and generates static electricity.
Static electricity stays in one place.
Electrons transferring between objects can result in a spark.
A spark is a brief electrical discharge.
Lightning is a large-scale example of static electricity, created by friction between water and ice in clouds.

Current Electricity

Current electricity involves a charge flowing along a path.
Wires are designed to carry electrical charges.
Materials that allow electricity to flow easily are conductors.
Turning on a light involves the charge flowing through the cord to the bulb.
Electricity is generated at power plants using turbines.
Power lines carry the generated electrical current to homes.
