Electrical Circuits

Front

What is an insulator?

Back

An insulator is a material that does not allow electricity to flow through it easily. Examples include rubber, plastic, and glass.

Front

What is a closed circuit?

Back

A closed circuit is a complete electrical circuit through which current can flow without interruption.

Front

What happens in a series circuit when more light bulbs are added?

Back

The current slows down and the lights dim lower because the total resistance increases.

Front

What is a conductor?

Back

A conductor is a material that allows electricity to flow through it easily. Examples include metals like copper and aluminum.

Front

What is a switch in an electrical circuit?

Back

A switch is a device that can open or close a circuit, controlling the flow of electricity.

Front

What is a parallel circuit?

Back

A parallel circuit is a type of electrical circuit where there are multiple paths for the current to flow.

Front

What is the role of a battery in a circuit?

Back

A battery provides the electrical energy needed to push the current through the circuit.

Front

What is the function of a buzzer in a circuit?

Back

A buzzer converts electrical energy into sound energy, producing a buzzing sound when current flows through it.

Front

What does it mean for a circuit to be open?

Back

An open circuit is one that is incomplete, preventing current from flowing.

Front

What is resistance in an electrical circuit?

Back

Resistance is a measure of how much a material opposes the flow of electric current, measured in ohms.
