41 Continuity Equation in Semiconductors | Derivation & Explanation | EDC

How do we mathematically represent the "Conservation of Charge" in semiconductors? ⚛️

In this video, we derive the **Continuity Equation**, which accounts for:
1. *Current Gradient* (Flow of carriers In/Out).
2. *Generation Rate* ($G$ - Creation of charges).
3. *Recombination Rate* ($R$ - Destruction of charges).
4. *Change with Time* ($dn/dt$ or $dp/dt$).



We explain the physical meaning of every term in the equation. Essential for GATE ECE, EEE, and Engineering Physics exams.
