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

• current electricity

• static electricity

• power source

• insulator

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
