• Water flows through a pipe

• Metal atoms move rapidly

What analogy is used to explain a closed circuit?

• A burning candle

• A bird flying

• Water flowing through a closed pipe

What is a flashlight that is off considered?

• A closed circuit

• A short circuit

• An open circuit

• A parallel circuit

How can open circuits be created accidentally?

• By pumping water through a pipe

• By closing a switch

• By using a light switch

• By forgetting to connect a battery

What is a short circuit?

• A connection between two points that should not be connected

• A circuit with a switch

• A circuit that uses a battery

• A circuit designed to save power

What does electric current do in a short circuit?

• Stops flowing

• Requires a switch to flow

• Takes the path of least resistance

• Flows through a light bulb

What can a short circuit cause?

• A peaceful, electrically neutral existence

• Water to stop flowing

• A flashlight to turn on

• A fire or explosion

What happens when you pump water through a closed pipe system?

• The water stops flowing

• Electric current flows

• The pipe breaks

• The water will flow as long as it's forced to move
