Aim:
After completion of the course a student is expected
- to understand fundamental laws of electromagnetism (Coulomb�?Ts law, Gauss law, Ohm�?Ts law, Amper�?Ts law, Faraday�?Ts law etc. ), as well as fundamental concept such as potential, capacitance, current, resistance, inductance, e.m.f., electromagnetic induction, etc.
- to be able to apply fundamental laws of electromagnetism to perform practical calculations (e.g. calculate potential, electric and magnetic fields, capacitance, inductance, e.m.f., etc. for basic model systems)
- to be able to relate fundamental laws of electromagnetism to various technological applications as well as to everyday life phenomena
- to be able to use the laws of electromagnetism in subsequent courses (such as Modern Physics, Semiconductor devices, Introduction to Material Science, Photonics etc.).
The course aims to give students knowledge of electromagnetism which is essential for continued studies in physics, esp. in the area of electronics.
