The book covers the major areas of physics that deal with electricity, magnetism, optics, and modern physics. It starts from the very basics—what charge is and how fields act around it—then moves toward more applied ideas like current, capacitors, circuits, electromagnetic induction, AC devices, and communication.
Once the electrical part is done, the book dives into how light behaves when it bends, reflects, and spreads. This includes both the simple straight-line model of light and the more complicated wave nature.
The final sections explore how particles such as electrons act like both waves and matter, how atoms are built, how nuclei behave, and how modern electronic components like diodes, transistors, and logic circuits work. The language is scientific but the flow is simple enough that anyone with curiosity can follow along.
