Circuits

Front

What is a circuit?

Back

A circuit is a closed loop that allows electricity to flow, enabling devices like lights to work.

Front

What are the main components of a simple circuit?

Back

The main components are a power source (like a battery), wires, and a load (like a light bulb).

Front

What happens when a switch is closed in a circuit?

Back

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

Front

What happens when a switch is open in a circuit?

Back

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

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 conductor?

Back

A conductor is a material that allows electricity to flow through it easily, such as copper wire.

Front

What is an insulator?

Back

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

Front

What is a load in a circuit?

Back

A load is any device that uses electricity to perform work, like a light bulb or a motor.

Front

How can you create a complete circuit?

Back

To create a complete circuit, connect a power source, wires, and a load in a closed loop.

Front

What is the function of a switch in a circuit?

Back

A switch controls the flow of electricity by opening or closing the circuit.
