Electrical Properties

material that allows the flow of charge

• Flow of - charged electrons, + holes, 1/- ions

Material with a high polarizability

• (Electrical resistance * cross section) / length

• The higher the moisture content the lower the resistance

• Measurement of electrical resistance to measure the moisture content

• Electical resestivity / thicknesss

1/resestivity

• Polymerization of pyrrole in wood cross sections of fir —> wood filled with tin-bismuth alloy

• Create electricity under mechanocal pressure
