Derivation of drift velocity class 12
WebIn this session, Educator Archana Pandey will be discussing Ohm's Law and Drift velocity from Current Electricity chapter for Class 12. Watch this complete v... WebAs the number of electrons is n A v d Δt, the charge ΔQ = n e A v d Δt. So I = ΔQ / Δt = n e A v d Δt / Δt = n e A v d. Thus it is clear that the current is directly proportional to the drift velocity of the electron. When the drift velocity is …
