Question

In this circuit, energy is transferred from a battery to a circuit wire and then to a light bulb, where some of it leaves the system. Starting from the battery, which series shows the correct order of energy transformations taking place in this circuit?

Answer 1

Answer: The correct order of energy transformation is from CHEMICAL ENERGY to ELECTRICAL ENERGY to LIGHT ENERGY

Explanation:

Energy which is simply defined as the ability to perform work is made up of different forms, these include:

- Mechanical energy: Associated with machines at work.

- LIGHT ENERGY: produced by light bulbs

- ELECTRICAL ENERGY: taking in by television set and other electrical appliances.

- CHEMICAL ENERGY: stores in food and other fuels

- Sound energy: Produced by vibrating objects example piano, drums.

According to the law of conservation of energy, energy can neither be created nor destroyed in a closed system, but can be transformed from one form to another, thereby keeping the energy in the closed system constant. From the question, the circuit is an example of a closed system and the order of energy transformation taking place is from the battery (CHEMICAL ENERGY) to ELECTRICAL ENERGY(power source) to LIGHT ENERGY(bulb). I hope this helps, thanks.
