Course Brief

Unit Abstract 

Electrical engineering is mainly concerned with the movement of energy and power in electrical form, and its generation and consumption. Electronics is mainly concerned with the manipulation of information, which may be acquired, stored, processed or transmitted in electrical form. Both depend on the same set of physical principles, though their applications differ widely. A study of electrical or
electronic engineering depends very much on these underlying principles; these form the foundation for any qualification in the field, and are the basis of this unit.

The physical principles themselves build initially from our understanding of the atom, the concept of electrical charge, electric fields, and the behaviour of the electron in different types of material. This understanding is readily applied to electric circuits of different types, and the basic circuit laws and electrical components emerge. Another set of principles is built around semiconductor devices, which become the basis of modern electronics. An introduction to semiconductor theory leads to a survey of the key electronic components, primarily different types of diodes and transistors.Electronics is very broadly divided into analogue and digital applications.

The final section of the unit introduces the fundamentals of these, using simple applications. Thus, under analogue electronics, the amplifier and its characteristics are introduced. Under digital electronics, voltages are applied as logic values, and simple circuits made from logic gates are considered.

On successful completion of this unit students will have a good and wide-ranging grasp of the underlying principles of electrical and electronic circuits and devices, and will be able to proceed with confidence to further study.


  • This course is offered in 45 hours.
  • BTEC Higher National Diploma (HND) in Engineering (Electrical and Electronic Engineering)

    The main aims of the HND in Engineering (Electrical and Electronic Engineering) are to:

    • Prepare students for a range of technical, professional and management career disciplines in Electrical and Electronic Engineering by providing specialised studies which are directly relevant to individual occupations and professions in which students are currently working or in which they intend to seek employment.
    • Enable students to make an immediate contribution in employment in the Electrical and Electronics sector.
    • Provide students with flexibility, knowledge, skills, understanding and motivation as a basis for progression to graduate and postgraduate studies.
    • Develop a range of skills and techniques, personal qualities and attitudes essential for successful performance in working life.

    Graduates of this HND Programme with a good grade profile will be able to access directly the final year of the University of Greenwich's BEng in Electrical and Electronic Engineering Technology at SBCS, Champs Fleurs campus.
