We introduce fundamental concepts, starting with protons, neutrons, and electrons, leading to molecules, crystals, etc., which leads to the difference between conductors and insulators. We consider voltage and current, resistance and resistors, capacitance and capacitors, and inductance and inductors. Next, we look at different ways to control electricity, from switches to relays to vacuum tubes to diodes and transistors. Finally, we see primitive logic functions like NOT, AND, and OR gates.
