Which of these is an example of a source? 

• A switch

• A Wire

• A light bulb

• A wall outlet

What is the source of energy in the circuits above? 

• light bulb

• battery

• wire 

• conductive object 

An object is added to the spot of circuit B. Why might the light bulb still not light? 

• the object added was an insulator 

• the object added was a conductor 

• the object was made of metal 

• the object created a closed circuit

A path along which electric charges can flow

• Series Circuit

• Circuit

• Parallel Circuit

• Conductor

A complete, connected circuit:

• Closed Circuit

• Open Circuit

• Conductor Circuit

Which is NOT a required part of a complete circuit designed to light a light bulb? 

• battery

• switch 

• wire

• light bulb 

The flow of electricity around a circuit

• Electrical Current

• Flow

• Electrical 

Olivia wanted to complete her circuit with a conductor.  What object is her best option?

• Wood stick

• Glass bead

• Aluminum foil

• Styrofoam

The picture shows an electrical circuit. This circuit is a series circuit because: 

• It has 3 light bulbs.

• The same current flows through all three light bulbs.

• It uses a single battery.

• The electrical current is divided between the three light bulbs.
