Consider an electrophysiology experiment in which a 0.200 mm diameter round silver wire is used as a stimulation electrode. In this experiment, a current of 3.77~ mA is applied through the wire. The density of free electrons in silver is 5.86 x 10^28 electrons/m^3 . Calculate the magnitude of the drift velocity of the electrons in the silver wire under these conditions. Enter your answer in units of meters/second using calculator scientific notation (e.g., 1.23e-4 for 0.000123).

2) The number density of conduction electrons in silver is 5.86 x 1028 m-3. independent of temperature. If a cylindrical wire of length L and cross-sectional area A were made of silver its electrical resistance would be given by R= ρ L A where ρ is the resistivity of the material measured in Ω−m. The resistivity can also be shown to be related to microscopic properties of the metal such as the number density of conduction electrons, the mass and...
