Which of the following materials is an electrical conductor?

• silver
• silver-colored plastic
• cork
• rubber

In which circuit will the bulb or bulbs glow brightest?

• A simple circuit with one light bulb and one battery

• A simple circuit with one light bulb and two batteries

• A simple circuit with two light bulbs and one battery

Why is a bulb brighter when it is powered by two batteries rather than one?

• Because the flow of electricity in the circuit is less
• Because the flow of electricity in the circuit is the same
• Because the flow of electricity in the circuit is greater
