What kind of electricity is natural (example: lightning)?

• current electricity

• static electricity

• power source

• insulator

What is the purpose of a fuse?

• to break the circuit and turn the power off if there is too much power being run

• to add more power to the circuit

• to be a conductor

• to be an insulator

A parallel circuit has more than one path for electricity to flow

• true

• false

Imagine you are creating a circuit. It works and the light bulb turns on. Then you add a piece of plastic to the circuit, and the light bulb does not turn on. We can infer that the plastic is

• an insulator

• a conductor

• an electron

• static electricity

If the light bulb turns ON in a circuit, that means the circuit is

• open

• closed

Items that have the same charge will do what?

• attract

• repel
