Lightbulbs, LEDs, and Circuits Quiz

What's the difference between LED bulbs and incandescent bulbs?

• LED bulbs are actually tiny wizards using magic gas to light up.

• Incandescent bulbs are the superheroes of energy efficiency.

• LED bulbs are marathon runners, lasting longer and sipping energy.

• Incandescent bulbs are tech geeks, using semiconductors to shine.

Which part of a circuit allows electricity to flow freely?

• Resistor

• Conductor

• Insulator

• Battery

What's the superpower of a resistor?

• To boost the electricity's power, making it zoom faster

• To gently slow down the electricity, keeping things safe

• To create an impenetrable barrier, stopping electricity in its tracks

• To act as a battery, storing electricity for later use

Which one of these is NOT going to help you conduct electricity?

• Copper

• Rubber

• Aluminum

• Gold

How do LEDs create light?

• By getting a filament super hot until it glows.

• By zipping electricity through a gas, making it glow.

• By mixing chemicals together for a glowing reaction.

• By letting electrons dance with electron holes, creating light with photons.

What is the superpower of the tiny wire inside a lightbulb?

• To reflect light

• To break the circuit

• To conduct electricity

• To produce light when heated

If a circuit is open, what happens next?

• The lightbulb will glow brighter.

• The lightbulb will not light up.

• The battery will recharge itself.

• The resistor will melt.

Why are LEDs considered eco-friendlier than incandescent bulbs?

• They can heat up your room faster.

• They secretly contain superhero gases.
