Circuits Review

Front

What is a closed circuit?

Back

A closed circuit is a complete electrical loop that allows current to flow, enabling devices like light bulbs to operate.

Front

What is an open circuit?

Back

An open circuit is a broken electrical loop that prevents current from flowing, causing devices to not operate.

Front

What is a conductor?

Back

A conductor is a material that allows electrons to flow easily, such as copper or aluminum.

Front

What is an insulator?

Back

An insulator is a material that does not allow electrons to flow easily, such as rubber or glass.

Front

What happens to a light bulb in a series circuit if one bulb goes out?

Back

In a series circuit, if one bulb goes out, all bulbs will go out because the circuit is broken.

Front

What happens to a light bulb in a parallel circuit if one bulb goes out?

Back

In a parallel circuit, if one bulb goes out, the other bulbs will stay lit because they have separate paths for current.

Front

Why is copper commonly used in electrical wiring?

Back

Copper is used in electrical wiring because it is an excellent conductor of electricity.

Front

What is the role of a switch in a circuit?

Back

A switch is used to open or close a circuit, controlling the flow of electricity.

Front

What is a series circuit?

Back

A series circuit is a type of circuit where components are connected end-to-end, so the same current flows through all components.

Front

What is a parallel circuit?

Back

A parallel circuit is a type of circuit where components are connected across common points, allowing multiple paths for current.
