Aims and learning outcomes
This unit is to introduce students to knowledge and techniques to analyse and solve problems in physics. This unit examines the laws and concepts involved in the areas of Electric Power, Magnetism and Light. Students will be introduced to knowledge and techniques to enable them to analyse and solve problems. Emphasis will be given to analysing and solving problems in context.
Students will carry out laboratory practical work to reinforce and place in context theory covered in lectures. The knowledge gained and the problem-solving skills developed will prepare students for undergraduate studies in engineering.
Students who successfully complete this unit should be able to:
- Apply the concepts of currents, resistance, potential difference and power to simple electric circuits.
- Analyse the effect of electric and magnetic field.
- Examine the generation, transmission and distribution of electrical power.
- Interpret and analyse the phenomena in wave model of light, and photo model of light.
- Conduct practical investigations safely and confidently, following instructions or guidelines and use appropriate terminology and format in reporting results of investigations.
