About the course

Electrical Energy is used everywhere affect every technical careers. This course will introduce some of the basics of electrical engineering theories & concepts. By participating in this course, you’ll gain a general understanding of the general concepts of electrical energy generation, transmission and distribution besides knowledge in the operating principles of relevant devices/equipments.

This most popular course focuses on the basic principles of industrial and commercial electrical power distribution. Your expect trainer will first help you understand basic concepts for the direct current case and then extend them to single-phase and three-phase alternating current. They will also develop basic electrical concepts such as power factor, kVA, kW, and inductive loads. Emphasis will be on understanding the basic phenomena rather than the rigorous mathematical derivations. Instruction will assume that you have no prior electrical engineering formal education but are currently working in the field.

Course Objectives

Upon completion of this course participants should:

  • Know the Basic Electrical Parameters (Voltage, Current, Resistance), their units of measurement (Volts, Amperes, Ohms) and inter-relationship (Ohms Law)
  • Be able to relate these parameters to the Basic Electrical Circuit and Series and Parallel Circuit configurations
  • Understand the difference between continuity and insulation resistance
  • Know how to calculate Electric Power and Energy consumption
  • Understand the information marked on equipment for rating purposes
