Which of the following best describes energy conservation as energy is transferred in the circuit?

• Energy is not created or destroyed. In the circuit, energy is transferred from electrical energy in the battery to electrical energy in the wire to light energy in the bulb.

• Energy is not created or destroyed. In the circuit, energy is transferred from chemical energy in the battery to electrical energy in the wire to light energy in the bulb.

• The chemical energy in the battery is destroyed, and new light energy is created in the bulb.

• The electrical energy in the battery is destroyed, and new chemical energy is created in the bulb.
