In the period of the 18th and 19th centuries, the concept of electrical conduction took place. And in the scope of electrical and physical engineering, conductors are most necessary to generate the current flow. The concepts of conductors, insulators and electric field came up with the thoughts and experiments done by many scientists and the person who stood behind the invention of these was Stephen Gray in the year 1734. From then the theories such as … [Read more...]
What is Electrical Conductivity : Working Principle, Formula & Applications
The history of electrical conductance invention takes back to the eighteen and nineteen centuries where Mr. Benjamin Franklin (1706–1790) observed that electrons could travel along the path of the metallic rod; which also resulted in the invention of a lightning rod. Mr. Alessandro Volta (1745-1827) studies on static electricity have led to the discovery of electric potential and the principle behind the development of batteries. Mr. Georg Simon Ohm … [Read more...]
