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

Which device or devices could be removed without breaking the electric circuit?

• Only the bulb

• Only the switch

• The battery and the switch

• The bulb and the switch

An electric circuit contains a battery, a switch, and a bulb. Which of the following will MOST LIKELY happen if you add another battery to the circuit?

• The bulb will shine brighter than it did with one battery

• The bulb will shine the same

• The bulb will shine half as bright as it did with one battery
