In 1979, Edison developed a carbon-filament lamp. He demonstrated operation of lamp at his Menlo Park laboratory. Very next year, he began producing lamps commercially in which he used carbonized bamboo as filaments. After finding that the oxygen weakens the platinum once it gets heated, he put the filament in a vacuum bulb. This surely improved the performance of his lamp. The market was eagerly waiting for a device that could solve their lighting needs. Edison applied the Joule’s and Ohm’s laws in developing high resistance lamps reducing the size of copper conductors and thereby its cost. He was the first person to convert carbon into a wire-kind . the invention helped him to make incandescent electric lamps providing one more utility that fulfilled market needs (Inventions (2012).&nbsp.&nbsp. Electric Power SystemWhen question comes to developing electric power system, he felt the need to develop host of other devices such as electrical generator, electric motors, fuses to prevent overloading, and the screw socket to hold lamps. Edison also designed a direct-current system that was required to provide power to an isolated single building. Soon he realized that an alternating current system was a better alternative for high-voltage transmission. He did not develop an alternating current system because he believed that high voltages were unsafe. His contribution to the development of electrical systems and devices is unprecedented.His only invention in the field of pure science came to be known as the Edison effect.
