What happens when a circuit is open?

• Electricity flows freely.

• The circuit is complete and devices can operate.

• Electricity cannot flow through the circuit.

• The circuit overheats.

A closed circuit means:

• The circuit is broken.

• The circuit is incomplete.

• The circuit is complete and electricity can flow.

• There is a short circuit.

Which of the following is NOT a property of conductors?

• They allow electricity to flow through them easily.

• They have high resistance.

• They can be metals like copper or aluminum.

• They are used to make wires and cables.

What does an insulator do in a circuit?

• Speeds up the electrical current.

• Allows electricity to flow freely.

• Stops or slows down the flow of electricity.

• Converts electricity into light.

Which of the following materials is a conductor?

• Wood

• Silver

• Styrofoam

• Porcelain

In a simple circuit, what component is necessary to control the flow of electricity?

• Battery

• Light bulb

• Switch

• Wire

What is the main difference between conductors and insulators?

• Conductors can only be solids, while insulators can be liquids or gases.

• Conductors allow electricity to flow through them, while insulators do not.

• Insulators can be charged electrically, while conductors cannot.

• Conductors are always cold to the touch, while insulators are warm.

Why are metals considered good conductors?

• They are shiny.

• They have high melting points.

• They contain free electrons that allow electricity to pass through easily.

• They are magnetic.
