Materials {conductor}|, such as metals, can allow electrons to move almost freely.
dipoles
Because electrons are free to move, no dipoles form. Conductor dielectric strength is zero, and dielectric constant is infinite, because charges can move freely. Rubbing metal with cloth cannot rub off charges, because electrons move freely and quickly in conductors.
spark
If charge touches conductors, electrons flow to neutralize charge, typically making sparks.
spread
Potential difference between conductor points is zero, because all electrons already repel each other equally. No electrons flow.
compression
Compressing metal increases conductivity, because crystals have fewer imperfections.
