Week 1: Parallel and Series Circuits-Knowledge Check Series

In a series circuit, what happens if one light bulb goes out?

• All the other lights stay on

• All the other lights go out

• The other lights blink faster

• The other lights get dimmer

In a parallel circuit, what happens if one light bulb stops working?

• All the other lights stay on

• All the other lights go out

• The other lights blink faster

• The other lights get dimmer

Why is the difference between series and parallel circuits important?

• It changes how bright the lights are

• It affects whether other lights work if one stops working

• It determines how many batteries are needed

• It has no impact on the circuit

You’re designing a greeting card with LED lights. Which circuit would you choose to make sure all the lights stay bright even if one goes out?

• Series Circuit

• Parallel Circuit

Why is this circuit the best choice?

• It makes the lights brighter

• It allows the lights to work independently

• It uses less energy

• It’s easier to build

How does a switch control the flow of electricity in your circuit?

• It blocks electricity completely

• It opens and closes the circuit to allow or stop the flow of electricity

• It changes the direction of the electricity

• It powers the circuit directly

Which of these devices uses a switch?

• A flashlight

• A remote control

• A table lamp

• All of the above

Which statement is true?

• The light bulb will light up because the circuit is complete.

• The light bulb will light up because the circuit is broken.

• The light bulb will not light up because the circuit is complete.

• The light bulb will not light up because the circuit is open.

What needs to be done to this circuit so that the lamp lights up?

• Close the switch

• Add a source and close the switch

• Add another lamp

• Add another lamp and a switch

Electricity that flows in a closed path is called a

• path
• current
• circuit
• light
