Front

What is a circuit?

Back

A circuit is a closed path through which electric current flows. It must be complete for devices like light bulbs to work.

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 wood.

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 battery?

Back

A battery is a device that stores chemical energy and converts it into electrical energy to power circuits.

Front

What happens in a closed circuit?

Back

In a closed circuit, the path is complete, allowing electricity to flow and power devices like light bulbs.

Front

What happens in an open circuit?

Back

In an open circuit, the path is broken, preventing electricity from flowing and devices from working.

Front

What is a light bulb?

Back

A light bulb is a device that converts electrical energy into light energy when electricity flows through it.

Front

What is the role of wires in a circuit?

Back

Wires connect different components in a circuit, allowing electricity to flow between them.

Front

What is a complete circuit?

Back

A complete circuit is one that has no breaks, allowing electricity to flow uninterrupted.
