Front

What types of energy can a circuit produce?

Back

A circuit can produce various types of energy, including thermal energy (heat) and light energy.

Front

What is an insulator?

Back

An insulator is a material that does not allow heat or electricity to pass through it easily.

Front

What is a conductor?

Back

A conductor is a material that allows electricity or heat to flow through it easily.

Front

What is the purpose of a circuit?

Back

The purpose of a circuit is to provide a path for electric current to flow, allowing devices to operate.

Front

What is the difference between renewable and non-renewable resources?

Back

Renewable resources can be replenished naturally, while non-renewable resources, like fossil fuels, cannot be replaced once used.
