Electrical Networks & Resonance SCQF Level 7

An HN unit designed to meet the learning needs of those on an HNC/HND electronics course.


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 will meet learning needs of candidates by exploring  electronic and electrical principles.

Studying this Unit will provide you with the opportunity to develop the knowledge, understanding and skills to apply network theorems to the solution of electronic and electrical circuits. Such theorems underpin much of the work in electronics, so it is important to have an in-depth understanding of these topics. 

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 study the behaviour of series and parallel electronic and electrical passive circuits at resonance. Such studies are important in helping you to understand how tuned circuits (such as those used in communication equipment) and some electronic filters work. A large emphasis is placed on putting your theoretical understanding into practice within a practical electronics and electrical context, in experiments and computer simulations on electronic and electrical circuits.

Throughout the course you will learn to apply a range of network theorems to the solution of d.c. and a.c. electrical network problems. You will also undertake a detailed study of series and parallel electronic and electrical passive resonant circuits, including the calculation of Q - factor and bandwidth and the plotting of impedance - frequency and current - frequency curves for both series, and parallel cases. By the end of this Unit you will be expected to apply network theorems to the solution of electronic and electrical network problems. You will also be expected to undertake detailed calculations and draw graphs associated with series and parallel electronic and electrical resonating circuits. 

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 this Unit.
