Alternating Current Fundamentals on-line e-learning cbt (computer based) : A transformer is an electrical device that transfers energy from one circuit to another purely by magnetic coupling. Transformers are often used to convert between high and low voltages, to change impedance, and to provide electrical isolation between circuits. A basic transformer consists of two sets of coils or windings close to each other (sometimes wrapped around an iron or ferrite "core"). Each set of windings is simply an inductor. Power is fed into one coil (the "primary"), which creates a magnetic field. The magnetic field causes current to flow in the other coil (the "secondary"). The alternating current that flows through the primary winding more...
Alternating Current Motors and Generators on-line e-learning cbt (computer based) : An alternating current generator, or AC generator, produces an alternating current, which means the voltage produced alternately reverses from positive to negative polarity, producing a corresponding change in the direction of current flow. Much like a DC generator, an AC generator requires a coil to cut across the force lines of a magnetic field. This coil is attached to two slip rings, which deliver the current to and from the load destination, thus completing the circuit. Alternating current generators are often called ? Alternators? . The magnitude of AC voltage generated by an AC generator is dependent on: The strength of the magnetic field (number of lines of force) more...

Direct Current Circuits Fundamentals on-line e-learning cbt (computer based) : Most students of electricity begin their study with what is known as direct current (DC). This is different than static electricity, which typically collects on the surface of a non-conductor such as a piece of plastic. It is also different than alternating current (AC) electricity, which flows back-and-forth in a conductor. In DC circuits, the polarity of the voltage source and current does not change over time. The direction of the flow of current in a circuit is always taken to be the direction in which a positive charge would move. By convention, we show DC current flow as originating at the positive terminal of the source, traveling through the circuit and returning to the negative more...

Electrical Conductors on-line e-learning cbt (computer based) : A conductor is a piece of metal used to conduct electricity, known colloquially as an electrical wire. Wires are very good conductors, which mean that they have very little resistance. In fact, their resistance is so small that often we consider it to be zero. (In other words, we often treat wires as perfect conductors). In the United States, conductors are measured by American wire gauge (abbreviated AWG) for smaller ones, and circular mils for larger ones.

An electronic device called a capacitor is designed to provide capacitance in an electric circuit by providing a means for storing energy in an electric field between two conducting bodies. A capacitor in its simplest form consists of two conducting plates separated by an insulating layer called a dielectric. When a capacitor is connected in a circuit across a voltage source, the voltage forces electrons onto the surface of one plate and pulls electrons off the surface of the other plate resulting in a potential difference between the plates. Capacitance is directly proportional to more...
Introduction to Electron Tubes on-line e-learning cbt (computer based) : An electron tube is a device used for the processing of electrical signals. Although solid state semiconductors have replaced the electron tubes in most applications, there are still niche applications where electron tubes not only continue to see practical use, but perform their respective tasks better than any solid-state device.

Design of Conduits Culverts and Pipes on-line e-learning cbt (computer based) : Overview The design procedure for conduits, culverts, and pipes vary due to life cycle considerations, material types used, loading types applied, and construction methods utilized. This course provides guidance on applying different types of loading such as (a) internal/external pressure, (b) vertical and horizontal pressures due to groundwater, surcharge water, and concentrated live loads, (c) trench earth loading with or without superimposed fill, and (d) embankment earth loads. In this course, the student will review Engineer Manual (EM) 1110-2-2909, "Engineering and Design - more...
Design of Crematories on-line e-learning cbt (computer based) : Overview Cremation is being used more and more in the United States. A crematory is essentially a pathological incinerator, and its characteristics, including air emission, are presented in this course. As cremation becomes more popular an understanding of the unique features of this technology and its application is of greater interest. The nature of the charge (the human body) and issues associated with its firing and combustion should be understood. To earn PDH credits for this course, the student must pass a multiple choice quiz of twenty(20) questions. Specific more...
Design of Roadside Channels with Flexible Linings Part 1 on-line e-learning cbt (computer based) : Overview Roadside channels play an important role in the highway drainage system as the initial conveyance for highway runoff. Roadside channels capture sheet flow from the highway pavement and backslope and convey that runoff to larger channels or culverts within the drainage system. This initial concentration of runoff may create hydraulic conditions that are erosive to the soil that forms the channel boundary. To perform reliably, the roadside channel is often stabilized against erosion by placing a protective lining over the soil. Channel lining materials fall into two classes: rigid or flexible channel linings. From an erosion control standpoint, the primary more...

Design of Small Water Systems on-line e-learning cbt (computer based) : Overview In this course the student will review EM 1110-2-503, "Design of Small Water Systems" published by the U.S. Army Corps of Engineers. This course is particularly relevant to engineers involved in designing both public and private water systems. Although the publication's title suggests coverage of only small water systems, much of the discussion applies to large systems as well. Below is a summary of the material covered by this course. The student must take a multiple-choice quiz consisting of forty questions at the end of this course to more...
Disinfection Methods for CSO Treatment on-line e-learning cbt (computer based) : Overview Combined sewer overflows (CSOs) occur when flows exceed the hydraulic capacity of either the wastewater treatment plant (WWTP) or the collection system that transports the combined flow of storm water and sanitary sewage to the WWTP. When an overflow occurs, the excess flows tend to be discharged into a receiving body of water. CSOs typically discharge a variable mixture of raw sewage, industrial/commercial wastewater, polluted runoff, and scoured materials that build up in the collection system during dry weather periods. These discharges contain a variety of more...
Drainage Design Truly Understand What Year Event Really Means on-line e-learning cbt (computer based) : Overview Hydrologic analysis and results are statistically based. The term 'year event' is the common way to express the hydrologic magnitude of precipitation and runoff quantities, but it does not tell the entire story. What does it really mean? Discussing drainage and flood issues with the general public and policymakers sometimes needs more than thinking just in terms of 'year event'. Its brevity in expression does not illustrate important considerations. One such is that the 100-year event has only a 63 chance of happening in 100 consecutive years yet can more...
