• A conductor such as a metal has high conductivity and a low resistivity. • An insulator like glass has low conductivity and a high resistivity. • The conductivity of a semiconductor is generally intermediate, but varies widely under different conditions, such as exposure of the material to electric fields or specific frequencies of light, and, most important, with temperature and composition of the semiconductor material. WebAug 14, 2003 · the resistance per 1000 feet of annealed copper wire at 20degrees C for AWG gauge numbers amazingly closely from the very simple formula, 10^(0.1*AWG-1), so for 10 gauge wire, it predicts 1 ohm, and my wire table says 0.9989 ohms and for 30 gauge it predicts 100 ohms, while the table says 103.2.
