Name severak conductors and insulators of electricity? How weel these substances conduct heat?

Answer 1

For table of resistivity go to http://en.wikipedia.org/wiki/Electrical_resistivity

Glass 1 E+ 12 to 1E+14 Resistivity ( in ohm m)

Mica 9 E+13 ohm m

Quartz (fused) 5 E+16 ohm m

This is compared to the resistivity of copper:

Resistivity (ohm m)
Copper 1.7 E -8 ohm m
Gold[1] 2.44 E-8 ohm m
