Electricity Unit Review

What does a D-cell do in a complete circuit?

• Provides electricity to the circuit

• Provides light to the circuit

• Provides wires

• Provides a pathway for electricity to flow

What do the wires do in a complete circuit?

• Provides electricity to the circuit

• Opens and closes the circuit

• Provides a pathway for the electricity to flow

• Provides light to the circuit

What is a conductor?

• completes a circuit and allows electricity to flow

• an object that stops the flow of electricity

• a device that used to open or close a circuit

• metal clip that connects wires

What is an insulator?

• battery

• completes a circuit and allows electricity to flow

• pathway for electricity to flow

• wood

• metal

• plastic

A toaster changes electric energy to

• sound energy

• magnetic energy

• solar energy

• heat energy

What is a parallel circuit?

• 2 or more receivers are connected in 1 circuit

• an object that stops the flow of electricity

• part of a bulb that gets hot and makes light

• splits into two or more pathway from the D-cell to the receivers

What will happen to the other two bulbs if the middle bulb burns out?

• They will go out.

• They will stay lit.

• One will go out, the other will stay lit.

• I don't know.

What is a series circuit?

• splits into two or more pathways from the D-cell to the receivers

• completes a circuit and allows electricity to flow

• 2 or more receivers are connected in 1 circuit

• provides energy to the light bulb

What does switch do?

• part of a bulb that gets hot

• hold many components needed for a circuit
