Electrical Circuits

Front

What is an electrical circuit?

Back

An electrical circuit is a closed loop that allows electricity to flow from a power source to an output device and back.

Front

What is a power source in a circuit?

Back

A power source provides the energy needed to move electric charges through the circuit. Examples include batteries and generators.

Front

What is an output device?

Back

An output device is a component that uses electricity to perform a function, such as a light bulb, motor, or speaker.

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 an insulator?

Back

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

Front

What does it mean for a circuit to be closed?

Back

A closed circuit means that there is a complete path for electricity to flow, allowing devices like light bulbs to turn on.

Front

What does it mean for a circuit to be open?

Back

An open circuit means that there is a break in the path, preventing electricity from flowing and devices from working.

Front

What is the role of a switch in a circuit?

Back

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

Front

What happens when a switch is closed?

Back

When a switch is closed, it completes the circuit, allowing electricity to flow and powering the output device.

Front

What happens when a switch is open?

Back

When a switch is open, it breaks the circuit, stopping the flow of electricity and turning off the output device.
