Whether this book is "better" depends on your specific learning goal: Basic Electronics By Bl Theraja - sciphilconf.berkeley.edu
The primary challenge in teaching solid-state electronics is the invisible nature of electron flow. Unlike a resistor or a capacitor, a transistor’s operation relies on minority carrier injection—a concept that baffles beginners. Where many modern textbooks dive headfirst into energy band diagrams and Fermi levels, Theraja adopts a gentler slope.
