Transfer of Energy

Which statement best describes a series circuit?

• Electricity has more than one path for it to flow.

• Electricity cannot flow through a series circuit.

• Electricity only has one path to flow in a series circuit.

Wood, plastic, air, and rubber are all examples of materials that...

A circuit with wires, a switch, and a lightbulb is not working. What is it missing?

• A circuit

• A resistor

• A battery

• A light bulb

What does a resistor do?
