Electrical Energy in Circuits

Which statement best defines a circuit?

• A path that electricity travels on

• A place where batteries are stored

• A switch that turns devices on and off

• A metal part that holds a light bulb

Which statements describe a closed circuit?

SELECT THREE CORRECT ANSWERS.

• It has no breaks, so current flows.

• The device connected is ON.

• It is an electrical path with a switch open, stopping flow.

• It is the same idea as a continuous closed path.

Match each term to its description.

• A path that electricity travels on

• Circuit

• A continuous loop that allows electricity to flow and power devices; also known as a closed circuit

• Closed circuit

• An electrical circuit with no breaks in which current flows; device is ON

• Closed path

Which of the following makes a circuit complete?

• It has at least one break so the switch can stop current.

• It has no breaks, allowing electric current to flow.

• It uses two batteries so the bulb is brighter.

• It contains only one wire and no components.

Which of the following statements describes a complete path in an electrical circuit?

• A path with gaps where electricity stops.

• A complete, unbroken path through which electricity can flow.

• A path made only of plastic parts.

• A path that works only when the battery is removed.

Which of the following are conductors?

SELECT TWO CORRECT ANSWERS.

• Copper wires that let energy pass easily

• Rubber tubing that blocks energy flow

• Steel nails that allow electricity to move

• Dry wood that prevents energy from passing

Which statement best defines electric current?

• The buildup of charge on an object that stays still

• The flow of electrons through a material, like a wire, that allows electricity to flow

• Energy stored in a battery without moving

• The brightness of a light bulb when connected to a circuit

Which phrase describes electricity?

• The movement of charged particles

• A form of energy created from the flow of charged particles through a conductor

• The force that holds atoms together

• A device that uses electrical energy to do work.
