Battery

Real World Example

Imagine trying to get through a long day without enough sleep, relying on caffeine to keep you energized. Just like how caffeine converts your fatigue into alertness, a battery converts chemical energy into electrical energy to power your devices. In this analogy, the caffeine is like the chemicals inside a battery, your energy boost is the electrical energy produced, and just as you are made up of cells, a battery is composed of multiple cells that work together to keep everything running smoothly.
