CFISD Electrical Circuits

What is a circuit with several paths for electricity to flow?

• conductor

• series circuit

• parallel circuit

• open circuit

A PATH along which electricity can flow is a ___________________?

• light bulb

• switch

• insulator

• circuit

What is a circuit that only has ONE path for electricity to flow?

• series circuit

• closed circuit

• parallel circuit

• light bulb

What is a circuit?

• an outlet or switch

• a path which an electric current flows

• a poor conductor

A student constructs the circuit shown for a science demonstration. With the switches in these positions, which lights are on? (a)  

• All the lights

• 1 and 2 only

• 3 and 4 only

• none of the lights

Which statement is true?

• The light bulb will light up because the  circuit is complete.

• The light bulb will light up because the  circuit is broken.

• The light bulb will not light up because the  circuit is complete.

• The light bulb will not light up because the  circuit is broken.

Match the following

• A path that is broken and won't allow electricity to flow through it.

• Switch

• A completed path that allows electricity to flow through it.

• Open Circuit

• Chemicals that react and give power. Example: batteries

• Closed Circuit

• A device that allows a circuit to be open or closed.

• Power Source

A series circuit has how many pathways for the electrons to flow?

• Two

• One

• Many

• Zero

Why electrical wiring usually are covered with a layer of plastic?

• To make it look pretty

• To help electricity flow along the wire

• To make it safe

• To add more energy

Which will light a bulb?

• A battery and a paper clip

• A battery and a wire

• A paper clip and a wire

• A switch and a wire
