Electric Circuits Quiz

Which of the following are the two basic components of an electrical circuit?

• A light bulb and a plastic spoon

• A cell (battery) and a switch

• A cell (battery) and a metal spoon

• A wire and an electrician

What would happen if a wire in a simple electric circuit doesn't connect properly?

• The bulb will shine brighter.

• The circuit will be complete, and the electricity will flow.

• The circuit will be incomplete, and the electricity will not flow.

• The bulb will only light up if you add more cells.

What will happen if another cell (battery) is added to a simple electric circuit?

• The bulb will become dimmer.

• The bulb will not light up at all.

• The bulb will shine brighter.

• The wire will disconnect from the bulb.

Which of the following best differentiates a conductor from an insulator?

• A conductor is a person, while an insulator is a material.

• An insulator allows electricity to pass through it, but a conductor does not.

• A conductor allows electricity to pass through it, but an insulator does not.

• Conductors and insulators are the same thing.

Which of the following are examples of electrical conductors?

• Plastic and glass

• Wood and rubber

• A plastic spoon and air

• Metals like copper and iron

Which of the following are examples of electrical insulators?

• Copper wire and a steel spoon

• Water and gold

• Plastic and glass

• A buzzer and a light bulb

In a circuit with a battery, a light bulb, and a plastic spoon, why would the bulb not light up?

• The bulb is broken.

• The battery is dead.

• The plastic spoon is a conductor and completes the circuit.

• The plastic spoon is an insulator, which prevents the electricity from flowing.

In a circuit with a battery, a light bulb, and a switch, why would the bulb not light up?

• The light bulb is broken.

• The switch is in the "off" or "open" position, which breaks the circuit.

• The battery is in backward.

• The light bulb is an insulator.

Katelyn wants to make her two bulbs shine brighter in her circuit. What is ONE way she can do this?

• She can add more connecting wires.

• She can add another light bulb.

• She can add another cell (battery) to the circuit.

• She can replace the bulbs with a buzzer.

• 80 kWh

• 25 kWh

• 35kWh

• 85 kWh
