What else can I help you with?
Is a lead of a pencil conductor or insulator.?
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.
Is a pencil lead is insulator or conductor?
Pencil lead is a conductor.
Is pencil lead a conductor of electricity?
yes pencil lead is a conductor it is made of graphite(a form of carbon) which is good conductor of electricity
What is the poorest electrical conductor is it pencil lead glass steel or aluminum?
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.
Is a pencil a good conductor of heat?
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.
Does pencil lead have coal in it?
No, modern pencil "lead" is actually made of a mixture of graphite and clay, not coal. Graphite is a form of carbon that is a good conductor of electricity and is commonly used in pencils due to its smooth writing properties.
What is the element of pencil lead?
The element of pencil lead is graphite, which is not actually lead but rather a form of carbon. Graphite is a good conductor of electricity and is commonly used in pencils due to its ability to leave marks on paper.
Is a pencil an insulator or a conductor?
Pencil "lead" is not really lead, the metal - Pb. Pencils are made with graphite which is a mineral, an insulator.
Is pencil lead a conductor?
Yes, pencil lead is a conductor of electricity. Lead is a metal. Most metals are good conductors of heat and electricity. Assuming of course you mean pencils back when lead was actually used as the writing medium in the pencil, then yes. Other than that, pencils nowadays are made using graphite as the writing medium. But graphite too can conduct electricity.
How does electricity flow through a pencil?
Electricity flows through a pencil when it is used as a conductor to complete a circuit. The graphite in the pencil lead allows electrons to flow through it, creating a closed path for the electricity to follow. This is possible because graphite is a good conductor of electricity.
Is a pencil a insulator or conductor?
Wood is a fair insulator, but graphite is a reasonably good conductor, so it depends on which part of the pencil you're measuring.
Why should a pencil never be used as a tool when working inside a computer?
Because pencil has graphite lead, which is a good conductor of electricity. Hence to avoid the shock pencils are avoided.
