it doesnot depend on meta l or non metal it depends on valence electron ........
Graphite conducts electricity because it contains delocalized electrons that are free to move across the layers of carbon atoms. These electrons can carry charge and enable the flow of current through the material, similar to the behavior of metals.
Graphite is the only non-metal exception that can conduct electricity. Hence, even though graphite is a non-metal, it is used in batteries.
Usually you need ions in order to conduct an electric current and distilled water only contains a very minute ion concentration. Once ions are added, though it can conduct electricity.
Yes, Pencil Lead does conduct Electricity. Copper, Gold and Silver though are the best conductors.
Pencil lead (aka graphite) DOES conduct electricity. It does this thanks to electron delocalization within the carbon layers. Since the valence electrons are free to move, they are able to conduct electricity.
Current travels through free electrons (These are present in most transitional metals and some allotropes of carbon (I.E. Graphite)), when there is a break in a circuit (No metal present) the current cannot travel the gap, unless it is of sufficient energy to "arc" through the air to connect the gap. However this will only occur if completing the circuit is the easiest and quickest way to ground itself (Hence why people get electric shocks, we, being made up of mostly water, conduct electricity better than air, so the current passes though us to ground).
Both
Materials such as metals (e.g. copper, aluminum) and conductive materials (e.g. graphite) produce heat energy when electric current is passed through them because of resistance. Resistance is the property that causes the material to hinder the flow of electrons, converting electrical energy into heat energy. This phenomenon is known as Joule heating.
No, graphite is not soft. In fact, if you find a graphite rock, it is extremely hard. It is often very colorful, though.
A poor conductor, like iron or steel.
Switches either allow the current to flow or turn it off
Whether a material is a conductor or an insulator depends on its ability to conduct electric current. An electric conductor is a material that allows the flow of electric charge. In conductors, electrons are loosely bound and can move easily, facilitating the flow of electric current. Common examples of conductors include metals like copper and aluminum. On the other hand, an insulator is a material that does not allow the flow of electric charge. Insulators have tightly bound electrons, and they do not conduct electricity well. Examples of insulators include rubber, glass, and most non-metallic materials. In the context of an electric press, it's important to note that the press itself is typically made of metal, which is a conductor. However, the material being pressed could be either a conductor or an insulator depending on its properties. If the material being pressed is an insulator, it won't conduct electricity well, even though the press itself is a conductor.
