b) When you use AAA battery in TV remote, where from the energy comes?

Answer 1

Answer:

Explanation:

​Where does energy come from? Energy comes from different sources such as oil, coal, wind, the sun, water, natural gas and even manure.

An AAA or triple-A battery is a standard size of dry cell battery commonly used in low-drain ... AAA batteries are most often used in small electronic devices, such as TV ... draw, are often designed to use larger batteries such as the AA battery type

Answer 2

The energy comes from:

(a) the combustion of paper.

(b) inside the chemicals of the cell.

- When we burn a paper an exothermic reaction takes place.

- Thus the combustion of the paper provides heat energy.

- When we use AAA battery in TV remote, then a chemical reaction takes place inside the battery.

- These reactions provide the electric energy to the remote to function.
