WebThe drift velocity is the average velocity attained by particles such as electrons under the influence of an electric field. The SI unit of drift velocity is m/s. It is also measured in m 2 / (V.s). Drift velocity can be calculated by the formula: I = nAv Q The derivation of drift velocity: F = - μE a = F/m = - μE/ m u = v + at WebMar 21, 2024 · Derivation of drift velocity. The average velocity gained by free electrons of a conductor is given by, v = I/ nAq. Where v is the drift velocity of electrons. I, is the current flowing through the conductor. A, the area of cross-section of the conductor. q, the charge on an electron. n, the number of electrons.
WebTo further understand the Drift of electrons and the origin of resistivity, you can assume a graph with the current (I) to the voltage (V) ratio. You will notice that the current will flow with the points A, B, and C, but this will slowly turn to a constant state after a matter of time.
