how can you make a own wet cell ? explain with the help of a diagram
Answers
Explanation:
A battery is a device that produces an electrical current by means of a chemical reaction. Though the first modern batteries were developed in the 19th century, there is some evidence to suggest crude wet cell batteries were produced at least 2000 years ago in Mesopotamia. As the name implies, a wet cell battery employs a liquid electrolyte-containing medium to trigger a chemical reaction. For example, in a lead acid battery, a liquid electrolyte solution containing 65 percent water and 35 percent sulfuric acid sits in contact with metal plates of lead and lead oxide. When the battery is connected, the acid bonds to the plates in a reaction that also sends an electric current through the attached circuit. If a battery can be recharged through the passing through it of a reversed current, separating the acid from the plates, then it is said to be a secondary battery, or rechargeable. Otherwise, if it is not rechargeable, it is a primary battery. If instead of a liquid solution the battery uses a pasty, less moist material, it is called a dry cell.
