This course introduces basic notions of Electric, Magnetic fields and circuits. Electric fields - Coulomb’s law, electric field & potential; Gauss’ law; capacitors and capacitance; Current of electricity; Ohm’s Law; Microscopic model of electrical conduction. Kirchoff’s laws; RC circuits. Magnetic fields – Biot-Savart’s Law and Ampere’s law; Lorentz force; Hall effect; mass spectrometer; JJ Thompson’s experiment; magnetic flux; Gauss’s Law of magnetism; Faraday’s and Lenz’s law; transformers; inductors and inductance. Electrical circuits - voltage, current and resistance; Oscillations in circuits - LC circuits and relative phases; complex current and voltage; complex impedance; LCR circuits and electrical resonance. High pass filters and low pass filters. Electromagnetic Waves – properties of electromagnetic waves; Poynting vector.
