Physics 8.05 - 8.08 Flashcards 'Electric Fields and Circuits'

Front

Where are electric fields found?

Back

Around every electric charge.

Front

What is an electric field?

Back

A region of space in which the effects of charge can be felt. When another charge enters the field, both charges interact and experience a force.

Front

Objects with the same charge...

Back

...repel.

Front

Objects with opposite charges...

Back

...attract.

Front

What is charging?

Back

The addition or removal of electrons from a material.

Front

How can charge be detected?

Back

Using a gold leaf electroscope; the gold leaf is repelled by positive charge or attracted to negative charge.

Front

What is charging by induction?

Back

When a charged object is brought near a conductor, attracting/repelling electrons in the conductor and causing a net charge to develop in the conductor as a result of electron distribution.

Front

What is a conductor?

Back

A material that can conduct electricity; electrons are able to flow through it.

Front

What is an insulator?

Back

An object that does not conduct electricity. Electrons cannot flow through the material.

Front

How is static electricity produced?

Back

When two insulators are rubbed together, transferring electrons to form a positive and a negative charge.
