Derive an expression for drift velocity of electrons in a conductor. Hence deduce ohm's law.

Microscopic Analysis OF Current Drift Velocity||Resistivity||Ohm's Law in Vector Form

Average and instantaneous current | Drift velocity | Mobility| Current density | Ohm's experimental law | Ohm's Law from drift velocity | Temperature dependence of resistivity for conductors | semi comductors and super conductors | Temperature dependence of resistance

State Ohm' law and deduce it from the knowledge of drift velocity of free electrons in a conductor carrying current.
