Basic Direct Current

The Basic Direct Current online PDH course is a part of the Electrical Engineering category of courses. This online course provides outlines of basic DC theory, its application and sources.

Direct current is used to charge batteries and as a power supply for electronic systems. Very large quantities of direct-current power are used in production of aluminum and other electrochemical processes. It is also used for some railways, especially in urban areas. High-voltage direct current is used to transmit large amounts of power from remote generation sites or to interconnect alternating current power grids.

This course is based on Module 2, “Basic DC Theory” of the Department of Energy Publication DOE-HDBK-1011/2-92, “Electrical Science”.

This course is intended for use by electrical engineers, design and construction professionals, students and others interested in learning about the AC concepts.

Learning Objectives:

Upon completion of this course, you will be able to:

  • Identify DC sources
  • Perform basic DC circuit calculations
  • Discuss voltage polarity and current direction
  • Apply Kirchhoff’s and Ohm’s laws
  • Perform circuit analysis
  • Describe voltage and current effects on open and shorted DC circuits
