Aluminum resistance aluminum shell.

Aluminum resistance of aluminum is the role of cooling, aluminum metal aluminum resistance is to form a group with the lattice structure of atoms, each atom has one (or more) of the electronic component shell. In the electronic case, from the nuclear attraction and flow everywhere, forming a electronic sea, the metal conductive aluminum resistance. When the applied potential difference (voltage) at the two ends of the metal, because the electric field, the influence of free electrons accelerated motion. But when the free aluminum electron and lattice collision kinetic energy, will suffer a loss, in order to release energy, so the form of energy, velocity of aluminum electronics is the average drift velocity, direction and the electric field in the opposite direction. Because the drift motion, can produce electric current. In reality, the atomic arrangement of materials can not completely rule, so the flow of electrons, will be arranged according to atomic scattering patterns, which is the source of aluminum resistance.
