An insulator restrictes electrical flow and a conductor allowes it.
Silk is an insulator, not a conductor. An insulator is something that does not allow electrical current to flow freely.
Diamond is a great conductor of heat, but a poor conductor of electricity.
Charcoal is an insulator. I had to use charcoal for a lab and see if it was a conductor or insulator, and we found out that it was an insulator since it can't help electrical/heat conductivity. -T :)
