5.6B Electricity 3

Which lightbulbs will remain lit when bulb 3 is unscrewed from the circuit?

• bulb 1 only

• bulbs 1 and 2

• bulbs 1, 2, and 4

• None of the bulbs

Which of the following materials is a good insulator of electricity?

• copper

• plastic

• gold

• steel

Study the picture. Which wires can be removed from the circuit without breaking the circuit?

• Wires 1 and 2

• Wires 2 and 3

• Wires 3 and 4

• Wires 4 and 5

Why doesn't the lightbulb shown below light up when used in a circuit?

• The flow of electricity needs a closed circuit and the lightbulb is broken.

• The flow of electricity needs a circular circuit and the lightbulbs is broken.

• The flow of light current needs a closed circuit and the lightbulb is broken.

• This type of lightbulb won't work in a curcuit.
