EAS 199A Lecture Notes: Basic Electricity Fall 2011 This course module introduces the basic physical models by which we explain the flow of electricity. The Bohr model of an atom – a nucleus surrounded by shells of electrons traveling in discrete orbits – is presented. Electrical current is described as a flow of electrons. Ohm’s law – the relationship between voltage‚ current and electrical resistance – is introduced. Learning Objectives Understanding the basic principles of electricity is

DeWolf felt that there was a problem in the market as many users had to build their own equipment to test as there was a lack of competent and capable producers in the semiconductor component testing field. These users and companies must use valuable time to make their own test equipment‚ which would incline them to purchase the equipment from an outside source. To establish themselves in the market‚ Teradyne focused on cutting

HOUSE WIRING Wiring is not a duck soup. Period. If you are among those freebies‚ who want to do wiring just because their neighbors are doing it‚ you are on a wrong trail. Wiring is a very serious subject and it’s better to get some information about basicelectrical wiring before you step into it. Any gaffe can burn down your beautiful house in a few minutes. It is a common fact that people get confused when they are cabling for the first time. Gathering some information about circuits‚ wires and

photovoltaic cell‚ also called a solar cell. Solar cells are made of the same kinds of semiconductor materials – a material that acts as electric insulator‚ such as silicon. For solar cells‚ a thin semiconductor wafer is specially treated to form an electric field‚ positive on one side and negative on the other. When light energy strikes the solar cell‚ electrons are knocked loose from the atoms in the semiconductor material. If electrical conductors are attached to the positive and negative sides‚
