Electricity and Magnetism

Which of the following is an insulator?

• an eraser

• a wire

• a metal spoon

• aluminum

Which of the following is a conductor?

• wood

• rubber

• metal

• plastic

This picture shoes a circuit that is

• closed

• open

• an insulator

• static electricity

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

Atoms that have the same charge will do what?

• attract

• repel

Items that have opposite charges do what?

• attract

• repel

• nothing changes

What type of electricity only has ONE path for the electricity to flow?

• series

• parallel

• none of the above

Electrons will move easily through aluminum. Based on this, we know that aluminum is a(n)

• conductor

• insulator
