Batteries 2

A detailed Summary of Batteries 2

The invention of batteries was considered a great discovery by affecting our lives. Has it affected our lives for good or for bad, since the discovery of batteries in around 1800? Before the time of invention a number of discoveries had previously been made. Floriano Caldani (1756) observed that frog legs could be made to contract when a near-by static machine was discharged. Luigi Galvani (1786) rediscovered this phenomenon and apparently unaware of similar work by Jan Swammerdam more than a century earlier (1678), noted that a contraction occurred without external electrical force, when two different metals were placed into the muscles of a dead frog. The physicist Alessandro Volta (1792) discovered the difference in potential of metals in contact with electrolyte and developed the concept of the electromotive series. By 1800 Volta had perfected and described the first operating battery or pile "which functions continuously, its charge being renewed after each discharge; it possesses in fine an inexhaustible charge."

Since this time a lot of changes have occurred within the technology of batteries throughout the world. Batteries have opened many doorways towards the future and better living. The improvement through the

The majority of people wear some form of watch on their wrist. The watches were first powered with the use of cogs where an operation which involved turning a knob on the side would 'wind' the watch up daily to keep it on time. This process would become annoying and with the invention of Silver cells the battery-powered watch was constructed. This let people keep the time handy for months, even years on end before the battery would eventually go flat and have to be replaced. The biggest disadvantage with this sort of cell is the fact that the discharging process could not be reversed to charge it again.

Batteries have already helped with the life quality of people around the world. Much of the quality has been for the human luxury although some less fortunate people have had their world enriched with a longer lifespan or just a higher quality of life. Adaptations will have to be made before the major energy contributors can be harnessed. Developments such as more powerful small batteries which discharging processes can be reversed need to be made to make batteries a better power storage source. When this is done the opportunities presented are endless.

Cars are a prime example of the technology of batteries affecting them. Cars used to run with the use of steam engines. The steam run cars could not move off instantly because of the time required to boil the water for the car to start producing steam. Technological advancements introduced the magneto, a magnetic rotor with the introduction of combustion engines. The magneto was introduced to provide the car with enough energy distributed to the spark plugs for ignition. This gave people the hassle of having to turn a rotor anytime they wanted to travel some
