Electricity and Static Electricity Flashcards

Flashcards about electricity and static electricity. These flashcards cover concepts like electric charge, conductors, insulators, electric force, electric fields, static electricity, charging methods (friction, conduction, induction), electric discharge, grounding, and applications of static electricity.

Electric Force

The force between charged objects; depends on the amount of charge and the distance between charges.

Electric Field

The region around a charged object where electric forces can be exerted on another charged object.

Static Electricity

Electric charge that builds up on an object that has gained or lost electrons and does not move along a wire.

Friction (Charging)

Charging by wiping electrons from one object onto another.

Conduction (Charging)

Charging by moving electrons from one object to another through direct contact.

Induction (Charging)

Charging by rearranging charges in an uncharged metal object without direct contact with a charged object.

Electric Discharge

The loss of static electricity as charges move off an object.

Grounding

Connecting an object to the earth through a wire, neutralizing the object.

Law of Electric Charges

Like charges repel; opposite charges attract.

Negative Electric Charge

Carried by electrons; negative electric charge.

Positive Electric Charge

Carried by protons; positive electric charge.

Electrical Conductor

Materials that allow electric charge to flow easily.

Electrical Insulator

Materials that resist the flow of electric charge.

Semiconductor

Materials that have properties of both conductors and insulators.

Static Electricity

Electric charge at rest on an object.
