Wet cell

A wet cell is a type of battery that works by using a chemical reaction to create electricity. Think of it like the battery in your toy car, but instead of being dry, it's wet with a liquid inside.

Inside the wet cell battery, there are two metal materials called electrodes (kind of like two different toys in your toy box). One of the electrodes is made of material that likes to give away electrons (we'll call it Toy A), while the other electrode likes to take in electrons (Toy B). Between the two electrodes is a liquid called an electrolyte, which helps the chemical reaction happen.

When the wet cell battery is connected to something like a toy car, the chemical reaction starts. Toy A starts letting go of electrons, which travel through a wire to Toy B. This flow of electrons is what creates the electricity that powers your toy car. Meanwhile, the electrolyte helps move charged particles around and keeps the chemical reaction going.

So, a wet cell is really just a battery that uses metal toys and a liquid to make electricity!
