Defination:-Ever wondered why people with tooth fillings sometimes
complain of getting an electric shock like sensation while they nibble on to
chocolates from the foil coating or from the silver on desserts? It is not just
a fleeting sensation, but is actually a minor electric current tantalizing the
nerves underneath the tooth. A momentary cell is formed between the foil
and the amalgam of the tooth filling with the acidic saliva acting like the
transport medium, the electrolyte.

History:-Electricity has been by far, one of the most important and novel
discoveries to mankind. With population getting increasingly mobile, they
have gravitated more towards portable solutions of electricity, which
manifests itself in the form of Batteries. Electricity has been around us since
the beginning of time, but its practical use has been at our disposal since a
few hundred years only.

While history stands witness to many artifacts such as the Parthian Battery
unearthed in Baghdad, which tell us that the concept had been existent
even in early civilizations like Egyptian and Babylonian, their use had been
limited to electroplating. In 1660, Otto von Guericke succeeded in
generating static charge in the form of sparks on rubbing and turning a
sulfur globe. In 1791, Luigi Galvani discovered animal electricity while
experimenting on a frog with metallic prongs. Prompted by the findings of
this experiment, Alessandro Volta, the inventor of the Electric Battery,
initiated a series of experiments using different metals and found out that
certain fluids could generate a continuous flow of electricity when used as a
conducting medium.
