DESCRIPTION
Problem 30981.
The current density in the wire (n = 2.2*10^23 cm^-3; p = 2.8*10^-6 Ohm*cm) is described by the equation j = e^-10t A/mm^2. Find: dependence of the speed of ordered movement of electrons on time; the amount of heat released into 1cm^3 of wire during the period of time from t1 = 0 to t2 = infinity.
