Now that … WebNCERT Solutions For Class 12 Physics; NCERT Solutions For Class 12 Chemistry; ... Derivation. Since, Drift velocity = Mobility × Electric Field. Therefore, Mobility (M) = Drift velocity × [Electric Field]-1. . . . (1) The dimensional formula of drift velocity = ...
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.
Webfinal velocity u = v+at Here v = 0, t = T, which is the relaxation time of electron Therefore u =aT, substitute in (2) ∴ u =- (μE/m)T Here, u is the Drift velocity, measured as m/s.
