Reference no: EM13662138

The resistance of an aluminum (L= 1 m and A = 1 mm2) wire is 0.0283 ohm. Evaluate the number of mobile electrons contributed by each Al atom. Assume the current is carried exclusively by electrons which have a mobility of 1.22X10-3 m2/(V-s). qe=1.6 x 10-19 C. Crystal structure is FCC, and the radius of Al is 0.143 nm.
