Drift Velocity Derivation in Nepali | Class 11 Drift velocity | Class 11 NEB physics |

The video begins with an introduction, likely setting the stage for the topic of drift velocity in the context of Class 11 physics.

The speaker explains the behavior of electrons and the influence of an external electric field on them, crucial for understanding drift velocity.

The concept of electrons undergoing collisions and their random motion within a conductor is discussed, leading to the idea of a net drift.

The video moves towards connecting the drift velocity of electrons to the current flowing through a conductor, using relevant physical quantities.

The core of the video, a detailed derivation of the drift current formula I = nAve, where I is current, n is electron density, A is cross-sectional area, v_d is drift velocity, and e is electron charge, is presented.
