@@^^** you ever wondered how a battery works? Well, it is actually very simple. A battery is mostly a tiny can full of chemicals. With these chemicals there is an acidic chemical that creates electrolytes. An electrolyte is any substance that contains ions that can conduct electricity. Also, with the chemicals in a battery, they create electrons. Electrons are a negative charge of electricity. On the outside of a battery there are marks that represent the positive part of a battery "+" and the negative part "-". These markings are called terminals. The flow of electrons from one terminal to another must go from negative to positive. This is how the battery is able to work. Inside a battery there is internal resistance, which is how fast electrons are created. This also controls how many electrons can flow between the terminals. The battery can only start a reaction to work, when a wire is connected to it. Batteries energy is called its voltage. Voltage is how much potential electricity something has, and it is measured in volts. There are many ways to make batteries that aren't as high in voltage as a regular battery. One of these ways is to create a lemon battery. The lemon battery has the same type of reactions as a regular battery just not as powerful.

A lemon battery is a great way to create a low voltage battery. To show that a lemon battery really works you would have to make more than one lemon and connect all the lemons, since there is such a low voltage. The voltage of one lemon is roughly around .8 volts. It also depends on the lemon itself. A lemon battery also produces low current. The current is the flow of electrons from the battery to the load. Plus, the load is what you are trying to power. With enough lemon batteries you could power a small LED light. The materials in creating your lemon battery are; a lemon, a copper penny, a zinc nail, a voltmeter, and alligator clips. Alligator clips can also be considered as wires, and it helps connect the battery to the load to be able to power. To make the lemon battery you would make to slits in the lemon a part from each other, and put the nail and penny in each one. Next, you would connect one alligator clip to both the nail and penny. Finally, you connect the alligator clips to the voltmeter. The voltmeter will read how much volts your lemon is producing. Now back to the fundamentals of the experiment. The lemon juice in the lemon acts as the electrolyte, like in a battery, the nail and the penny act as the electrodes. Electrodes are a type of an electrical conductor that helps transfer electricity when it is inside a nonmetallic object, such as the lemon. So, the nail and the penny actually act as a bridge between the lemon, to the alligator clips which is connected to the load. The nail and penny are very essential, since the electrons wouldn't be able to travel to the load. Then, no electricity would flow into the load, resulting in an open circuit. A lemon battery will be a low volt, low current battery, that won’t power all that much. It would take multiple lemons just to power a small LED light. And even with a good amount of lemons, you could not power something like a hot plate. In the end a lemon is good way to make a battery of your own, but it is not so sufficient.
