A 0.69 −mm -diameter copper wire carries a tiny current of 2.0 μA .
The maximum rated current for a copper wire of cross-sectional area 2 mm^2 is 20A. (a) What is the corresponding current density in A/m^2? (b) On the assumption that each copper atom contributes one conduction electron, calculate the electronic drift velocity corresponding to this current density. (Avogadro's number = 6.02E10^23 atoms per mole; atomic weight of copper = 63.5; density of copper = 8.92 g/cm^3.) (c) Use the observed conductivity to calculate the average collision time for an electron in...
