Graphite conducts electricity.
insulator
The shell or carapce made of wood in pencil having a graphite refill in it is an insulator but as graphite is good conductor of electricity so overall a pencil can cunduct current in it.
semi conductor
No. Lead is a realtively good conductor. The insulator is the wood on the outside of the lead.
a conductor is anything metal and an insulator is anything rubber
Graphite conducts electricity.
Graphite is a conductor of electricity, but its conductivity varies greatly with direction: Conduction is high along the plane of the sheets of carbon atoms found in a single crystal of graphite, but much lower perpendicular to this plane.
see, the pencil's outer shield is made out of wood which is a bad conductor of electricity but the graphite core is a good conductor. thank you.

semi conductor
Diamond is considered the hardest mineral known to man, while graphite is one of the softest. Diamond is an excellent electrical insulator, while graphite is a good conductor of electricity. This is due to the way the carbon atoms are arranged in each mineral.
No. Lead is a realtively good conductor. The insulator is the wood on the outside of the lead.

A carbon rod may be an insulator or a conductor. It depends on which allotrope of carbon we're talking about. Electricity can travel through a graphite (carbon) rod easily, but it cannot travel through a diamond rod. Both graphite and diamond are carbon, but the former is a conductor while the latter is an insulator.
Paper is an insulator of electricity.
Wood is a fair insulator, but graphite is a reasonably good conductor, so it depends on which part of the pencil you're measuring.
