Study Chapter Details
UP Board Class 12 Physics – Semiconductor Devices
The chapter “Semiconductor Devices” in UP Board Class 12 Physics introduces students to the materials and devices that form the backbone of modern electronics. It explains intrinsic and extrinsic semiconductors, their electrical conductivity, and the role of doping in creating n-type and p-type semiconductors.
Students learn about important semiconductor devices such as p-n junction diodes, their characteristics, and applications, including rectifiers (half-wave and full-wave). The chapter also covers Zener diodes and their role in voltage regulation.
Other devices discussed include junction transistors, their working as amplifiers and switches, and the basics of LEDs, solar cells, and photodiodes. This chapter provides a strong foundation for understanding modern electronics, communication systems, and practical applications in daily life.
Numerical problems, circuit diagrams, and practical applications make the chapter highly relevant for board exams and competitive tests like JEE.
