A current of 0.105 mA flows in a silver wire whose cross-sectional area is 0.930 mm2. (The resistivity of silver is 1.62 10-8 ? m, and the density of silver is 10.49 g/cm3.)
(a) Find the density of electrons in the wire, assuming that there is one conduction electron per silver atom.
(b) Find the current density in the wire assuming that the current is uniform.
(c) Find the electron's drift speed.
