Answer to Question #202295 in Physics for Tulimeke

Question #202295

The conductivity of silver is 6.5 x 107per Ohm per m and number of conduction electrons per m3 is 6 x 1028. Find the mobility of conduction electrons and the drift velocity in an electric field of 1 V/m. Given m = 9.1 x 10–31 kg and e = 1.602 x 10–19 C.

The drift velocity:


"v_d=\\frac{\\sigma E}{ne}=6.76\u00b710^{-3}\\text{ m\/s}."

The mobility:


"\\mu=\\frac{v_d}{E}=6.76\u00b710^{-3}\\text{ m}^2\/\\text{Vs}."
