Batteries

I am constructing batteries for my science fair project. My problem statement is, “does the fluid affect the power in a battery? “.

My first Article is on batteries. There are two main types of batteries, primary and secondary. Primary batteries are not rechargeable and secondary batteries are. Batteries include a positive and a negative charge. These are completely opposite from each other like Republican and Democrat or chocolate and vanilla and therefore push away from each other. To use the power in a battery you must have a conductor. The most commonly used conductor is copper. I am using copper wires in my experiment to connect them to an amp. Conductors help carry electric currents.

My second article is on electricity. Electricity, in a nutshell, is just a reaction to charged particles. A flow electricity is called an electric current. Electric currents are what flow through power lines to power our homes and other electronic devices like chargers and televisions. Just like with batteries, which are like electricity in a little container, there are positive and negative charges. This article also taught me about electrical shock and how they are electric currents passing through the body. These currents can disrupt other signals like the beating of the heart and signals from the brain or to the brain. Definitely something I want to avoid by taking extra safety precautions.

My third article is on fuel cells. Fuel cells transform chemical energy into electrical energy. To do this, they must constantly be fed fuel, thus being named fuel cells. It also needs an oxidizer, which removes the electrons from a chemical reaction. Fuel cells are very expensive. You can’t just go out and buy one. In 1960, a couple of United States’ space programs used fuel cells to power electrical power for a spacecraft. My point is, space programs have millions of dollars, and they can afford fuel cells.
