Understanding Static and Current Electricity

Electricity built up on a surface is known as what?

• Current electricity

• Static electricity

• Dynamic electricity

• Alternating electricity

Define static.

• Moving rapidly

• Not moving or to remain the same

• Changing constantly

• Flowing continuously

Where does static electricity develop?

• Only in conductors

• Only in insulators

• In both conductors and insulators

• In neither conductors nor insulators

What flows through current electricity?

• Protons

• Neutrons

• Electrons

• Photons

Which of the following is a difference between static and current electricity?

• Static electricity allows electrons to flow, while current electricity builds electrons up.

• Static electricity occurs only in conductors, while current electricity occurs in both conductors and insulators.

• Current electricity allows electrons to flow, while static electricity builds electrons up and they remain still.

• Both static and current electricity occur only in insulators.
