Abigail is working on a science project and has set up a simple electric circuit with a light bulb. Describe what happens when she turns off the switch in the circuit.

• The circuit remains closed, and electricity continues to flow.

• The circuit opens, and electricity stops flowing.

• The circuit becomes overloaded.

• The circuit becomes a conductor.

Why is it important for a circuit to be closed for electricity to flow?

• To prevent electricity from escaping

• To allow the current to complete its path

• To increase the voltage

• To decrease the resistance

Explain why rubber is used to cover electrical wires.

• Rubber is a good conductor of electricity.

• Rubber is a good insulator and prevents electric shocks.

• Rubber increases the flow of electricity.

• Rubber is cheaper than other materials.
