Circuits

Why does the following circuit not work?

• The light bulb is broken

• The switch is closed

• The wood block is an insulator

• The battery is dead

The circuit does not work, what could you do to allow the circuit to work?

• Add another light

• Add another battery

• Open the switch

• Remove the wood block and connect the wires

Which lights would turn on if your closed switches 1 and 2?

• red, blue, and white

• red and white

• red and blue

• blue, white, yellow

What forms of energy are you using if you close switch 1?

• light and electrical

• light, sound, and electrical

• light

• sound

The light bulb does not turn on, which statement explains why it is not working?

• The battery is dead

• The light bulb is broken

• The bell is taking all of the energy

• The light bulb is not part of a complete circuit

Which wire would you need to cut in order for the circuit to be incomplete (not work)?

• wire 1

• Wire 3

• wire 5

A material that does NOT let electricity pass through it is called ...

• electrical conductor

• Battery

• electrical insulator

• light bulb

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.

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.

Does this diagram represent a series or parallel circuit?

• series circuit
• parallel circuit
