Our Electrical Principles course will equip learners with the knowledge, skills and competencies in the principles underpinning the functioning of electrical circuits. An understanding of fundamental principles leads to a true understanding of electrical hazards and will result in safer working practices.

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.

Course Objectives

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

Entry Requirements

Module # /

No previous formal qualification is required but learners should have relevant work or life experience to have reached the standards of knowledge, skill and competence associated with Level 5 of the National Framework of Qualifications.

Though no specific qualification is required entrants should have some prior technical or mechanical experience or knowledge. Ideally they would have had exposure to electrically controlled equipment and/or a manufacturing environment. We will speak to each applicant by phone to determine entry level and course suitability. This course is an ideal companion course to the QQI Level 6 Industrial Electrical Systems programme.

Competence in written and spoken English is essential. International students whose first language is not English are required to have an appropriate score in an approved examination in English language. We accept an IELTS test score of 6. We also accept IELTS equivalents such as TOELF and Cambridge exams. If learners do not have a test result they can complete a Duolingo English Test before registering on the course.  Applicants must share their Duolingo Online test score directly with us at grace@technotraining.ie .  The test can be taken online, costs US$49 and the result is available within 48 hours. englishtest.duolingo.com/applicants

If learners are completing part, or all, of the course online they should have good computer literacy skills. This includes use of email, microsoft word, internet searches. Self-directed learning also requires learners to have good self motivation and time management skills. Again, further details and tips can be found in the Learner Handbook.

If you are participating in a blended learning programme you will be required to have a laptop or desktop computer.

If you would like to assess your entry level knowledge, relative to course content, please contact us and we can set you up with a free trial on our e-learning platform.

RPL is a process whereby a learner with prior qualifications and/or relevant work experience may apply to exemptions from attending the full course. Note learners will still need to pass the assessments. You will be asked to submit an application form for RPL and will be required to provide proof of qualification. RPL requirements are different for different courses and awards.

When we receive your booking request we will call you to go through an enrolment checklist with you to ensure that you meet all entry requirements for the course you have selected.

If you have any questions before making a booking request, we’d love to hear from you.
