Objectives
This module covers the basic physical principles involved in the function of key electronic devices and electrical systems.Learning outcomes
On completion of this module students should be able to:
1. Explain the relationship between electric fields, charges and currents, potential difference and work done on a charge and solve well-defined problems involving these quantities.
2. Describe the basic properties of materials which govern electronic and magnetic phenomena.
3. Explain the concept of electromagnetic induction and the relationship between current, magnetic field and motion, and solve well-defined problems involving these quantities.
4. Explain the differences in the conducting properties of insulators, semiconductors and metals in terms of electron energy bands.
5. Explain how the conductivity in semiconductors is affected by light and temperature, and how it can be engineered by adding controlled amounts of impurities.
6. Describe the materials structure and physical operating principles of basic diodes.
7. Interpret the mathematical representation of a travelling wave.
8. Explain the basic concept of an electromagnetic wave in free space.
9. Explain the need to account for electromagnetic phenomena in high-frequency circuit design.
