Energy and Circuits

Front

What is energy transfer?

Back

Energy transfer is the process of moving energy from one place to another or changing it from one form to another.

Front

What is a closed circuit?

Back

A closed circuit is a complete electrical loop that allows current to flow.

Front

What is an insulator?

Back

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

Front

What is an example of electrical to thermal energy transfer?

Back

An example is a toaster, which converts electrical energy into thermal energy to toast bread.

Front

What type of energy is given off by a fire?

Back

A fire gives off light, thermal (heat), and sound energy.

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 the difference between conductors and insulators?

Back

Conductors allow electricity to flow easily, while insulators do not.

Front

What is an example of a good conductor?

Back

Copper is a good conductor of electricity.

Front

What happens in a series circuit?

Back

In a series circuit, all components are connected in a single path, so the same current flows through all of them.

Front

What happens in a parallel circuit?

Back

In a parallel circuit, components are connected across common points, allowing multiple paths for current to flow.
