Energy Transfers and Transformations Quiz

Which of the following best describes how energy is conserved in an electrical circuit?

• Energy is created and destroyed as it moves through the circuit.

• Energy is transferred and transformed but the total amount remains constant.

• Energy is only transferred without any transformation.

• Energy is lost as it moves through the circuit.
