Those who should attend
This course is ideally suited to those who want to develop knowledge of the basic concepts of electrical engineering principles in order to understand and predict how electromagnetic devices and electrical circuits will operate within their workplace and have the ability to communicate effectively with colleagues regarding electrical issues.
Why should I attend?
An understanding of the relevant concepts and theories of electromagnetic devices and circuits is the foundation needed for the correct operation of measuring instruments which are of vital importance in all AC and DC electrical circuits and equipment. In addition, the ability to understand electrical schematics and circuit diagrams is a key skill for maintenance technicians. The Electrical Principles course is an ideal foundation for the Industrial Electrical Systems course as it equips learners with a solid understanding of the operating principles of electrical circuit components and the skills to navigate electrical schematics. This knowledge will underpin the fault-finding and diagnostic skills that are developed in the Industrial Electrical Systems module.
At the end of the course learners will be able to:
- • Understand how to describe the characteristics of conductors and insulators and the underlying atomic structure that govern these characteristics.
- • Understand the units and characteristics of electrical circuits and the laws that govern their relationship to each other.
- • Understand the behaviour of various electrical components including capacitor, inductors, transformers, and the laws that govern their behaviour.
- • Outline the functioning of electrical circuits under direct current and alternating current conditions.
- • Understand the consumption of power in electrical circuits, and the factors that affect it.
- • Calculate the values of various characteristics given sufficient information.
- • Understand the construction of basic electrical circuits.
- • Use electrical test meters to diagnose and resolve problems with the functioning of electrical circuits.
- • Demonstrate an ability to read and draw circuit diagrams.
- • Resolve circuit malfunctions, applying a systematic, logical, and analytical approach.
- • Interpret test results
