Learning Outcomes
On successful completion of this module, a student will be able to:
Teaching Methods
Lectures will be used to introduce new material and provide examples. During tutorials and workshops students will attempt to solve problems and apply the theory presented during the lectures. Moreover, practical sessions will be used to develop competences in three main areas:
a) Familiarisation with and use of electrical laboratory equipment.
b) Implementation and measurement of various electrical quantities using various instruments.
c) Familiarisation with software tools for the design and simulation of electrical circuits.
Assessment Methods
This module is assessed through a practical assignments in the class and a final exam.
