⚡ From AC to DC — Discover How Rectifiers Power Modern Electronics!
In this Class 12 Physics lesson by NextLeap.AI, we explore one of the most practical applications of the p–n junction diode — Rectification. You’ll learn how diodes convert alternating current (AC) into direct current (DC) using half-wave and full-wave rectifier circuits, and how filters smooth the output for steady DC supply.
We’ll analyze waveforms, rectifier efficiency, ripple frequency, and filtering mechanisms, alongside key formulas and a solved numerical example. This lesson connects theory to real-world use — from mobile chargers to power adapters — helping you visualize how simple semiconductors make modern electronics possible.
Perfect for CBSE, JEE, and NEET aspirants, this concept builds your understanding of rectifiers, filtering, and power conversion step by step.
