236 - How does a battery produce electrical energy?

A battery produces electrical energy through a chemical reaction inside it. Here's a simplified explanation:

1. A battery has two main parts: positive (called the cathode) and negative (called the anode).
2. These parts are separated by a special liquid or gel that helps the chemical reaction.
3. When you connect a battery to a device (like a flashlight), the chemical reaction starts. The cathode and anode start to talk to each other through the liquid.
4. As they "talk," tiny particles called electrons start moving from the anode to the cathode.
5. This movement of electrons is what we call electricity.
6. The electrons keep flowing until the chemical reaction runs out, and the battery is empty.

Think of it like a tiny factory inside the battery, where chemical reactions create electricity that powers your devices.
