Front

What is a circuit?

Back

A circuit is a closed path through which electric current flows.

Front

What is an insulator?

Back

An insulator is a material that does not allow electricity to flow through it easily.

Front

What is a conductor?

Back

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

Front

What happens when a switch is closed?

Back

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

Front

What happens when a switch is open?

Back

When a switch is open, it breaks the circuit, stopping the flow of electricity.

Front

What is a battery?

Back

A battery is a device that stores electrical energy and provides power to a circuit.

Front

What is a light bulb?

Back

A light bulb is a device that converts electrical energy into light.

Front

What materials are needed to create a complete circuit?

Back

You need a power source (like a battery), a conductor (like copper wire), and a load (like a light bulb).

Front

What is the role of a switch in a circuit?

Back

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

Front

What is the difference between series and parallel circuits?

Back

In a series circuit, components are connected one after another, while in a parallel circuit, components are connected across the same voltage source.
