When electric current in a material is proportional to the voltage across it, the material is said to be "ohmic", or to obey Ohm's law. A microscopic …
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 … Web6 jan. 2024 · Electron mobility is how quickly an electron can move through a conductor. It's determined by the drift velocity and the strength of the electric field as shown in this …
WebIt is because the Fermi energy of Au is about twenty times larger than that of Pb, and, as a consequence, the drift mobility of randomly moving charge carriers in Au is about twenty times higher than one in Pb. This expression is well known for metals and is obtained by solving the kinetic equation [2,3].
