Electric Circuits Quiz

What is a circuit?

• A component that opens and closes the circuit

• A pathway for the flow of electric current

• A circuit with one pathway

• The place where connections are made to allow electricity to pass

What is the role of a switch in a circuit?

• A pathway for the flow of electric current

• A circuit with 2 or more pathways

• A component that opens and closes the circuit

• An item in a circuit

What defines an open circuit?

• A complete circuit through which electricity can flow

• A circuit with one pathway

• A circuit with 2 or more pathways

• An incomplete circuit through which electricity cannot flow

What is a closed circuit?

• A circuit with one pathway

• An incomplete circuit through which electricity cannot flow

• A complete circuit through which electricity CAN flow

• A circuit with 2 or more pathways

What distinguishes a series circuit from a parallel circuit?

• A series circuit has a component that opens and closes, while a parallel circuit does not.

• A series circuit has one pathway for electricity, while a parallel circuit has two or more pathways.

• A series circuit allows electricity to pass through contact points, while a parallel circuit does not.

• A series circuit cannot have an open or closed state, while a parallel circuit can.

What does a conductor allow?

• Electricity to pass through

• Heat to pass through

• Sound to pass through

• Light to pass through

What is an insulator?

• A material that allows electricity to pass through

• A material that allows heat to pass through

• A material that does NOT allow electricity to pass through

• A material that allows sound to pass through

What are the terminals of a battery?

• The negative ends of the battery

• The positive ends of the battery

• The positive and negative ends of the battery

• The neutral points of the battery

What is the evidence of energy transfer in a circuit?

• Sound

• Motion (moving)

• Heat

• Light

In a simple circuit with a D-cell and a lightbulb, where does electricity flow out of?

• The positive terminal of the battery

• The negative terminal of the battery

• The bulb base

• The bulb casing
