The role of aluminum shell aluminum shell


The role of aluminum in the aluminum shell resistor is cooling. The aluminum metal in the aluminum shell resistor is a group of atoms that form with the lattice structure, and each atom has a shell of one (or more) electronic components. In the case of electronics, from the attraction and flow of the nucleus, an electronic sea is formed so that the metal aluminum shell resistance can conduct electricity. When the potential difference (ie voltage) is applied to the ends of the metal, because of the influence of the electric field, the accelerated movement of free electrons. However, when the free aluminum electron collides with the crystal lattice, the kinetic energy will suffer loss. In order to release the energy, so the formal energy, the movement speed of the aluminum electron is the average drift velocity, the opposite direction and the electric field. Due to drifting motion, current can be generated. In reality, the material arrangement of atoms cannot be completely regular, so the way of electron flow will be arranged according to the law of atom scattering, which is the source of aluminum shell resistance.
