Web7 jul. 2024 · So I attached the standard derivation of the relationship between drift velocity and electric field. Tau=s/Vd, where s is the mean free path of the electron. Substituting this into the Vd= (...) equation, we should get that E is actually proportional to (Vd)^2. Tau is not actually a constant as it's implied but it's dependent on the velocity. WebThe battery voltage creates an average electric field within the conductor of length , and it is this field that exerts a driving force on the free charged particles within the conductor, each of charge , and pushes them through the wire. The charged particles collide with the atoms in the wire. The collisions produce an average “drag” force helmiäinen
