Electrical Circuits

Front

What is an electrical circuit?

Back

An electrical circuit is a closed path through which electric current flows.

Front

What is needed for a circuit to work?

Back

A complete circuit requires a power source (like a battery), conductors (like wires), and a load (like a bulb or buzzer).

Front

What does it mean if a bulb does not light up in a circuit?

Back

It may mean that the circuit is incomplete or that there is a break in the path.

Front

What is a complete circuit?

Back

A complete circuit is one where electricity can flow uninterrupted from the power source, through the load, and back to the power source.

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 materials can conduct electricity?

Back

Materials that can conduct electricity include metals like copper and aluminum.

Front

What is an insulator?

Back

An insulator is a material that does not allow electricity to flow through it, such as rubber or yarn.

Front

What happens when a switch is closed?

Back

When a switch is closed, it completes the circuit, allowing electricity to flow.

Front

What is the role of a battery in a circuit?

Back

A battery provides the electrical energy needed to power the circuit.

Front

What is a load in an electrical circuit?

Back

A load is any device that uses electricity to perform work, such as a light bulb or buzzer.
