Overview
This package has been specially designed by PDHengineer.com to provide 10 PDH at a highly discounted price. And, if you Refer a PE, you can get a FREE 1 PDH Ethics course as well. You could save up to 38% on PDH credits guaranteed to be accepted by your state board.
The package consists of two of our most popular Electrical Engineering courses in one easy-to-complete package that will earn 10 PDH.
Course 1 - Direct Current Circuits: Fundamentals (6 PDH)
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 terminal. The main source of DC is from batteries, photocells, fuel cells, rectifiers and DC generators.
This 6-hour course provides the basic fundamental concepts, laws and terminology as they relate to DC circuits. This course will help readers gain an understanding of resistance, voltage, and current in series and parallel direct current (DC) circuits.
The course material is based entirely on Naval Education and Training Materials (NAVEDTRA 14173), Electricity and Electronic Training Series; Module-1 “Introduction to matter, energy and direct current” and covers Chapter 3, “Direct Current”. The text is arranged to let you progress at your own pace, and concepts and terms are introduced as you need them, with many detailed examples and illustrations. This course will be extremely helpful to electrical engineers looking for a refresher course in direct current, as well as engineers in other disciplines who would like to expand their knowledge in fundamental electrical engineering concepts.
The student must take a multiple-choice quiz consisting of thirty (30) questions at the end of this course to obtain PDH credits.

- State the meaning of the term "equivalent resistance"
Course 2 - Basic Direct Current (DC) Theory (4 PDH)
Direct current or DC electricity is the continuous movement of electrons from an area of negative (-) charges to an area of positive (+) charges. A DC circuit is necessary to allow the current or stream of electrons to flow. Such a circuit consists of a source of electrical energy (such as a battery) and a conducting wire running from the positive end of the source to the negative terminal.
DC circuits may be in series, parallel or a combination. Understanding DC circuits is important for learning about the more complex AC circuits. This course introduces the basic electricity and electrical circuit concepts associated with direct current. Topics include calculation of current, voltage, resistance and power in series, parallel and combination circuits with direct current (DC) power sources.
The 4-hr course material is based entirely on US Department of Energy training materials DOE-HDBK-1011/1-92, Fundamentals Handbook, Electrical Science; volume 1 of 4 and covers module 2, Basic DC Theory.
