Pencil lead is the poorest electrical conductor among the materials listed. While steel and glass are poor conductors, aluminum is a relatively good conductor of electricity.
Pencil "lead" is not really lead, the metal - Pb. Pencils are made with graphite which is a mineral, an insulator.
Note: "electricity" is not conducted, only electrical current (the flow of electrons) is. Electricity is the field that covers all things electrical. The wood in a pencil is an insulator. If it is wet, it is a poorer insulator, but only a poor conductor. The carbon (lead) in the pencil is a poor conductor. The metal holding the eraser is a good conductor. The rubber eraser is a poor conductor. You really have to address the conductivity of specific substances, not items that are build from a variety of substances.
Electric currents will not flow through a pencil because the graphite in a pencil is not a good conductor of electricity. Graphite is considered a semiconductor, so it does not allow electricity to flow as easily as a metal conductor.
No, the lid of a pencil (usually made of plastic or metal) is not a good conductor of electricity compared to metals like copper or aluminum. Conductivity depends on the material's ability to allow electrons to flow through it, which is higher in metals than in plastics.
A lead of a pencil is a conductor because it is made of graphite, which allows electricity to flow through it. Graphite is a good conductor of electricity due to the free movement of electrons in its molecular structure.

No, a pencil is not a good conductor of heat because it is made of graphite, which is a poor conductor of heat. Heat will not travel easily through a pencil, making it a good insulator rather than a conductor of heat.
insulator bcz its a bad conductor.....
Doubt it
Wood is a fair insulator, but graphite is a reasonably good conductor, so it depends on which part of the pencil you're measuring.
insulator bcz its a bad conductor.....
yes pencil lead is a conductor it is made of graphite(a form of carbon) which is good conductor of electricity
