Static Electricity Review and AC DC_25

Front

What causes the movement of electrons in a Direct Current?

Back

The steady pull of electrons along the wire.

Front

If two charges repel each other, what can we infer about the charges?

Back

The two charges must be negative and negative.

Front

What is the major difference between static electricity and current electricity?

Back

Current electricity involves a flow of electrons; static electricity involves a single transfer of electrons.

Front

When you pull a cotton sweater off your skin, what happens to the charges?

Back

Electrons are transferred from the skin to the cotton, resulting in the body acquiring a positive charge and the cotton sweater acquiring a negative charge.

Front

What happens when you rub a glass rod with a piece of silk?

Back

The silk becomes negatively charged.

Front

Define static electricity.

Back

Static electricity is the accumulation of electric charge on the surface of objects.

Front

Define current electricity.

Back

Current electricity is the flow of electric charge through a conductor.

Front

What is an insulator?

Back

An insulator is a material that does not allow electric charges to flow freely.

Front

What is a conductor?

Back

A conductor is a material that allows electric charges to flow easily.

Front

What is the role of electrons in electricity?

Back

Electrons are the negatively charged particles that flow to create electric current.
