- How Transistors Work
How transistors switch and amplify electrical signals using semiconductors — MOSFET operation, logic gates, and why billions of them fit on one chip. - How the Power Grid Works
How the power grid delivers electricity from plants to homes — generation, high-voltage transmission, grid balancing, frequency control, and transformers. - Ohm's Law
The linear relation between voltage, current, and resistance — V = IR — that is fundamental to circuit analysis. - Kirchhoff's Circuit Laws
The two conservation laws that govern every electrical circuit: current conservation at nodes and voltage conservation around loops. - Three-Phase Electric Power
Why the world's power grids use three phases: constant power delivery, rotating fields, and cheaper conductors.
