Semiconductor Electronics | Class 12 Physics | PYQs + Complete Concepts | Board Exam 2026 I Live

Описание: In this lecture, we cover Semiconductor Electronics: Materials, Devices and Simple Circuits (Class 12 Physics) with complete concept clarity and board-oriented explanation, strictly as per the CBSE & MP Board syllabus 2026.

This chapter is one of the most scoring units in modern physics and is heavily asked in numericals, theory questions, and PYQs.

🔹 Topics Covered:
• Energy bands: conductors, semiconductors & insulators
• Intrinsic & extrinsic semiconductors
• n-type and p-type semiconductors
• p-n junction diode & its working
• Zener diode and voltage regulation
• Rectifiers (Half & Full Wave)
• LED, Photodiode, Solar Cell
• Logic gates (AND, OR, NOT)
• Important derivations & diagrams
• Concept-based PYQs (CBSE & MP Board)

This session is ideal for:
✔ Class 12 Board Exam 2026
✔ NEET & JEE foundation students
✔ Last-minute revision
✔ Numerical + theory balance
