A pencil can be both. It is an insulator if you use the wood side and a conductor if you connected to the metal side.

Semiconductors like silicon can exhibit properties of both conductors and insulators depending on their doping level. Graphite is a good conductor of electricity due to its free delocalized electrons, but it also acts as an insulator in the perpendicular direction. Metal oxides like zinc oxide can conduct electricity at high temperatures, but behave as insulators at lower temperatures.

What are some houshold objects that are conductors or insulators?
If you can think of any objects that are made of glass, rubber, or plastic they are all insulators. (think of food containers things you drink out of -most of them are conductors) Most things made of metal are conductors. (metal things you eat with, metal furniture objects, anything copper)
Are all objects considered conductors?
No, not all objects are considered conductors. Conductors are materials that allow the flow of electricity, such as metals like copper and aluminum. Insulators, on the other hand, are materials that do not allow the flow of electricity, like rubber and plastic.
What are some insulators and conductors?
Insulators: rubber, plastic, glass. Conductors: copper, aluminum, gold.
Why conductors conduct heat and electricity while insulators are known as poor conductors?
Conductors have free electrons that are able to move easily and transfer heat and electricity. In contrast, insulators have tightly bound electrons that do not move easily, so they are unable to conduct heat and electricity effectively. This is why conductors are efficient at transferring heat and electricity whereas insulators are poor conductors.
What are the classification of materials according to electrical conductivity?
Materials can be classified into three categories based on their electrical conductivity: conductors, insulators, and semiconductors. Conductors have high electrical conductivity, allowing electric current to flow easily through them. Insulators have very low electrical conductivity, preventing the flow of electric current. Semiconductors have an intermediate level of electrical conductivity, between that of conductors and insulators.

Are keys insulators or conductors?
Keys are usually made from some metal or alloy. If they are, they are good conductors, both of heat and of electricity.

Is a phone a insulator or conductor?
some parts are insulators, some parts are conductors
Why some of the materials are insulators?
They are bad conductors ,they do not allow heat transfer.
What items are insulators and conductor?
Conductors are materials that allow electrons to flow easily through it. Metals are the best examples of conductors. Insulators to the opposite; they don't like letting their electrons flow. Glass, rubber, and wood are some examples of insulators.
What are conductors and insulators of electricity?
Conductors are materials that pass electrical current easily, that is, with low resistance. Insulators are materials that do not pass electrical current easily, that is, they have high resistance. Conductors are ordinarily metals, and insulators are ordinarily nonmetals. Some examples of conductors are: Silver, Copper, Carbon, and Aluminum. Some examples of insulators are Glass, Nylon, and Wood (as well as Air and Vacuum). Conductivity is a function of the mobility of Electrons in the materials in question. Conductors have high mobility and conductors have low mobility. Semiconductors are materials that have some properties of both conductors and insulators. Germanium and Silicon are well known semiconductors. Superconductors are materials that pass electrical current with zero resistance. All known superconductors perform this function only at very low temperatures, far below those encountered in Earth environments (i.e. from around 77 degrees above absolute zero down, or, in other words, below about -320 degrees F).

Is a tire a insulator or a conductor?
Regular car tires are insulators. Some aircraft tires are conductors.
