3. I. Development of Electricity A. Michael Faraday- made key discoveries 1. Explored the nature of electricity. Prior people thought electricity was like a liquid that ran through pipes 2. Discovered that moving a magnet through a coil of wire produced electric current 3. Developed first dynamo(electric generator) a. Transformed mechanical energy into electrical energy

4. II. Edison and the light Bulb A. Thomas Edison 1. Created a bulb that burned for two days before going out 2. Developed a system for transmitting electricity from a central powerhouse B. Electric motors replaced steam engines in factories. 1. Why? C. Water Power- Hydroelectric power was sent long distances through wires

5. III. Communications A. Alexander Graham Bell 1. Patented his telephone in 1876 2. Used electrical circuits to transmit the human voice B. Guglielmo Marconi 1. Studied the ideas of James Maxwell who said there were electromagnetic waves that travel through space at the speed of light 2. Developed a way to send messages without wires 3. Invented wireless telegraph for sending and receiving radio waves

6. IV. The Internal Combustion Engine A. Automobiles 1. 1893 Charles and Frank Duryea built first successful gasoline-driven car 2. Henry Ford produced first commercially successful automobile the Model T B. Airplanes 1. Wilbur and Orville Wright- first to achieve a sustained controlled flight 2. The y used the technology of the internal combustion engine to propel their plane
