Electricity was first researched by Thales of Miletos around 600BC. He conducted a few experiments on static electricity in which he believed that friction made amber become magnetized. Other than the fact that people knew that eels produced electric shocks‚ electricity was little more than an intellectual curiosity for over 2000 years. Until 1600 when someone from England discovered the lodestone effect when amber with static would attract small objects towards it. In the 18th century‚ Benjamin

Introduction Wireless network is indicated to a telecommunication network whose interconnections between nodes are implemented without the use of wires‚ such a computer network. Nowadays‚ wireless network has become the important thing in telecommunication. This sort of technology has been used for over a century and remains synonymous with radio. In 19th century‚ Guglielmo Marconi invented a radio and made his made his mark in the world of wireless technology. At that moment‚ Marconi was about

HISTORY OF ELECTRICITY Depite what you have learned‚ Benjamin Franklin did not "invent" electricity. In fact‚ electricity did not begin when Benjamin Franklin at when he flew his kite during a thunderstorm or when light bulbs were installed in houses all around the world. The truth is that electricity has always been around because it naturally exists in the world. Lightning‚ for instance‚ is simply a flow of electrons between the ground and the clouds. When you touch something and get a shock
