WebAboutTranscript. Drift velocity is the average velocity with which electrons 'drift' in the presence of an electric field. It's the drift velocity (or drift speed) that contributes to the electric current. In contrast, thermal velocity causes random motion resulting in collisions with metal ions. Created by Mahesh Shenoy. WebThe drift velocity therefore can be calculated: Dimensional analysis : Therefore, in this wire, the electrons are flowing at the rate of 23 μm/s. At 60 Hz alternating current, this means that, within half a cycle, on average the electrons drift less than 0.2 μm. introduction to jowarWebeasy way to understand the drift velocity and effect of temperature on it new orleans breakers logo
