Unit7 Assignment 1 #1 transmission lines are specialized cables and other media designed to carry alternating current and electromagnetic waves of high frequency (radio frequency or higher)‚ high enough that its wave nature must be taken into account. #3 Solid dielectric cable has become the national standard for underground electric transmission lines less than 200 kV. There is less maintenance with the solid cable‚ but impending insulation failures are much more difficult to monitor and detect

ACTI VE M AGNETI C BEARI NGS (AM B) A magnetic bearing is a bearing which supports a load using magnetic levitation. Magnetic bearings support moving machinery without physical contact‚ for example‚ they can levitate a rotating shaft and permit relative motion without friction or wear. In active magnetic bearings (AMB) a stable equilibrium is achieved by means of one or more control loops. The use of control loop for maintaining the gap between the shaft and bearing differentiate the active

Although some physical issues appear to be difficult to understand‚ explain James Kakalios achieved from conduction and convection to modern physics. It is much easier to learn when it comes to something you love‚ that’s why the lessons presented in the book seemed understandable. One of the first issues of the second half of the work are phase transitions. Reading the title of the section I figured it would be a very complicated and it would take me a long time to know the subject. I realized‚ the

Unit 51: Electrical Technology P1 describe the characteristics and principles of operation of a DC electromagnetic generator. A DC electromagnetic generator produces direct power and also‚ electrical power (just like the AC generator). It is also produced based on same fundamental principle of Faraday’s Law of Electromagnetic induction where whenever a conductor cuts magnetic flux‚ dynamically induced electromotive force is produced‚ and this causes current to flow if the conductor/conductors is

For our project we decided to disassemble and understand a Memphis 1 Channel Mono Block Amplifier. First we started by disassembling the amp down to the main circuit board. From there we assigned ourselves different components to understand what they were and how they worked inside the amp. We all researched our components and got back together to discuss and figure out the flow of power and operations of the amp worked. A general idea of what the amp does is as follows. Power comes into the inputs

PHY124- C1 date performed: 5/22/13 Rousselle Molina date submitted: 5/29/13 ELECTRIC FIELD MAPPING I. ABSTRACT: In the Electric Field Mapping‚ we used charged electrodes to create an electric field on a glass tray with a piece of linear graph paper attached to the bottom. We tested several simple electrode positions by moving the probes and drew equipotential lines based on the voltage difference. We then confirmed that the equipotential lines run perpendicular to electric field
