Module Title:Principles of Electricity
Language of Instruction:English
Credits: 10
NFQ Level:6
Module Delivered In 2 programme(s)
Teaching & Learning Strategies: (a) Teaching will be conducted using lectures, tutorials and practicals. (b) The Institute MLE will be used to evaluate the students understanding of the basic concepts during each section using multiple-choice questions. (c) At the end of each section, self-test question sheets will be issued to the students. Any difficulties arising from the self-test question sheets will be addressed during the following tutorial. (d) At various stages of the module students will be directed to certain websites and will have to research certain topics (given exact research criteria). These topics will form the basis of discussion in a tutorial session. (e) The practical sessions will be used to back up the theory.
Module Aim: To give the students an understanding of the concept of an electric circuit and its associated parameters. To develop their ability to analyse the behaviour of electric circuits, to apply circuit theorems to simplify basic electric circuits and to analyse basic electromagnetic circuits.
