Electricity

This circuit is _________.

• open

• parallel

• closed

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 has more than one path to flow through

This picture is an example of what kind of circuit?

• Series
• Complete
• Broken
• Parallel

What will happen if one light bulb is removed from this circuit?

• The other bulbs will go out.
• The other bulbs will stay on
• The other bulbs will get dimmer.
• The battery will become stronger.

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
