A material that does not allow electrical charges to move easily.

Front

What is the role of a conductor in an electrical circuit?

Back

To allow the flow of electric current.

Front

What is static electricity?

Back

An imbalance of electric charges within or on the surface of a material.

Front

What is the difference between conduction and induction?

Back

Conduction is the direct transfer of electrons through contact, while induction is the transfer of charge without direct contact.
