Why take this course?

This Unit was developed for the HNC/HND Electronics Group Awards or may be taken as a stand alone HN Unit. It has been designed to allow you to develop knowledge, understanding and skills in basic electrical and magnetic concepts and theorems, that underpin so much of more advanced studies in electronic and electrical engineering.

A strong emphasis is placed on putting your theoretical knowledge – within a practical electronics and electrical context – into practice, as you will be provided with the opportunity to conduct practical experiments and computer simulations on electronic and electrical circuits. If you have studied these subjects before, the early parts of this unit will provide you with an opportunity to revise the electrical concepts and theorems you have learnt in previous courses.

Credit points and level: 1 HN credit at SCQF level 7: (8 SCQF credit points at SCQF level 7)

What you will experience

You will get the opportunity to study the ways in which resistance-inductance and resistance — capacitance series electrical circuits respond to the sudden application or removal of a DC voltage, for example when a switch is closed or opened in such circuits. This in turn will introduce you to the ideas of transient responses that are so important in so many branches of engineering. You will develop the necessary knowledge and skills to solve single-phase ac circuit problems using complex notation – a powerful tool for solving a range of ac circuit problems. A good grasp of this tool will allow you to solve complex problems involving combinations of series and parallel impedance. You will also examine first order transient responses as found in r-l and r-c series circuits.

By the end of the Unit you will be expected to solve simple electrical and electronic problems using basic electrical concepts and theorems. You will also be expected to sketch the graphs associated with resistance-inductance and resistance-capacitance series circuits when a dc voltage is suddenly applied or removed from these circuits. You will also be expected to use complex notation to solve a range of single-phase ac circuit problems.

The formal assessment will consist of a single assessment paper lasting one hour and thirty minutes. The assessment will be conducted under closed-book conditions in which you will not be allowed to take notes, textbooks etc. into the assessment. However, you will be allowed to use a scientific calculator. You will sit this assessment paper at the end of the unit.
