Define mean drift velocity

WebI = Δ Q Δ t = qnAx Δ t. Note that x/Δt x / Δ t is the magnitude of the drift velocity, vd v d, since the charges move an average distance x x in a time Δt Δ t. Rearranging terms gives. I = nqAvd, I = n q A v d, where I I is the current through a wire of cross-sectional area A A made of a material with a free charge density n n. WebHere, u is the Drift velocity, measured as m/s. This gives the final expression. The SI unit of drift velocity is m/s or m 2 /(V.s) & V/m. Drift Velocity Formula. This formula is used to find the drift velocity of …
