Introduction to Electrical and Electronics Engineering

The laws that let you find every current and voltage in a network, and two systematic methods that scale when inspection stops working. Then the magnetic analogue, where the same algebra reappears with different names, and the induction laws that connect the two worlds.

Why the grid is alternating and three-phase, and the mathematics that makes alternating quantities tractable. RMS values that let AC and DC be compared honestly, phasors that turn calculus into algebra, and the power triangle that explains why industrial consumers are billed for their power factor.

The heaviest module in the course by teaching time, and the one the exam weights the same as every other. Diodes and rectifiers first — which overlap with Physics, so the notes point there rather than repeating — then the transistor, from its characteristics to the load line that decides where it sits, and finally the field-effect devices that displaced it in digital electronics.

The lightest module at nine hours, and worth the same nine marks in the exam as the thirteen-hour one before it — the best return on revision time in the paper. Block diagrams rather than derivations: how a message gets from one place to another, how instruments measure what the earlier modules describe, and where the whole subject is actually applied.
