Electricity and Series Circuits Quiz

What is the simplest type of circuit to make?

• Alternating circuit

• Complex circuit

• Series circuit

• Parallel circuit

What is necessary for a circuit to work?

• A single wire

• A switch

• A complete circuit

• Multiple batteries

What happens to the brightness of the globes when more are added in series?

• They remain the same

• They become brighter

• They become duller

• They flicker

Why do the globes become duller as more are added in series?

• Less electricity is available

• The wires are longer

• More resistance is added

• The battery is weaker

What happens if one globe is removed from a series circuit?

• All globes go out

• The remaining globes become brighter

• Only that globe goes out

• The circuit becomes faster

Why are series circuits not ideal for household lighting?

• They are too expensive

• They are too bright

• If one light goes out, all go out

• They require too many wires
