What will a student most likely observe in a circuit with a battery, two light bulbs, and a switch if the switch is closed?

Back

Light bulb 1 will be on, but light bulb 2 will be off.

Front

What is the most likely reason a light bulb is not lit in a circuit?

Back

The switch is left open.

Front

Why is copper commonly used for electrical wiring?

Back

Because copper conducts electricity.

Front

What happens to a light bulb if a paper clip is replaced with a plastic spoon in a circuit?

Front

What is the role of a switch in an electric circuit?

Back

To open or close the circuit, controlling the flow of electricity.

Front

What is the effect of using an insulator instead of a conductor in a circuit?

Back

The circuit will not allow electricity to flow, and the bulb will not light.

Front

What is a closed circuit?

Back

A closed circuit is a complete electrical loop that allows current to flow.

Front

What is an open circuit?

Back

An open circuit is a broken loop that prevents current from flowing.

Front

How does the arrangement of components in a circuit affect the operation of light bulbs?

Back

In series, bulbs share voltage; in parallel, each bulb gets full voltage.
