Introduction to Electronics

Introduction to Electronics History n In 600 BC Greeks discovered static electricity by rubbing wool against amber which would attract objects. n Amber is the common name for fossil resin or tree sap that is appreciated for its inherent and interesting mixture of colors and it is widely used for the manufacture of ornamental objects. Although not mineralized, it is sometimes considered and used as a gemstone. Most of the world's amber is in the range of 30– 90 million years old. Semi-fossilized resin or subfossil amber is called copal.

Introduction to Electronics Types of Electricity n Two forms of electricity Static and Produced n Static Electricity is an electrical charge at rest. n Produced Electricity is produced by either magnetism, chemicals, light, heat, or pressure.
