DC AC Principles SCQF Level 7
Apply basic electrical concepts and theorems for the solution of electrical problems.
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.
It would be an advantage for candidates to have a basic knowledge and understanding of electrical, electrostatic and magnetic concepts and theorems, although this is not absolutely essential, as some of these concepts and theorems are revised in the first Outcome. Possession of basic knowledge and understanding of these concepts and theorems may be evidenced by possession of a Higher in Electrical Engineering or the following National Qualification units:
- D136 12 AC Circuit Theory and Applications
- E9RR 12 Circuit Elements
- E9RS 12 DC and AC Circuit Responses
- E9RV 12 Electromagnetics
- E9RW 12 Electrostatics
- E9RX 12 Network Analysis
- E9S0 12 Single Phase AC
It may also be an advantage for candidates to take the Mathematics for Engineering 1: Electronics and Electrical before this unit, as it contains an outcome on complex numbers which would underpin much of the work involved in the second outcome of this unit.

If you take up a place on a College course, at the start of the course you will be asked to sign an enrolment form. In signing the form and/or taking up a place on a College course, you will enter into a contract with the College and be bound by the North East Scotland College Standard Terms and Conditions of Study. Copies of the Terms and Conditions are available for inspection on notice boards and at various locations throughout the College, at the College Reception, on the College website: www.nescol.ac.uk, or can be obtained on request from the Student Funding and Admissions Manager, North East Scotland College, Aberdeen City Campus, Gallowgate, Aberdeen AB25 1BN. Please note that courses are offered subject to (a) there being sufficient numbers of enrolments and (b) the availability of resources. The College reserves its right (i) not to run courses where the number of students is considered insufficient or where resources are unavailable and (ii) in certain circumstances, to refuse admission to an individual applicant.
For distance learning courses, the course fees for non-Scottish residents may differ from that advertised on the website and in the course guide. Therefore, all course fees should be confirmed with the College at the time of booking.
