Why semiconductive materials do not conduct current well?
Semiconductive materials do not conduct current well because their valence band is mostly filled and their conduction band is mostly empty, requiring an input of energy for electrons to move from the valence to the conduction band and thus carry a current. Additionally, semiconductors have a wider band gap compared to conductors, which further restricts the flow of electrons.
In order to conduct an electric current a substance must contain a what?
It should contain some IONS, or charged particles.
What are ALL the materials that can conduct electricity?
Some materials that can conduct electricity include metals such as copper, silver, and aluminum, as well as carbon in the form of graphite. Conductivity is based on the availability of free electrons within the material to carry electric current.
What has the ability inability to conduct an electrical current is called?
A material's ability to conduct electricity is determined by its conductivity. Materials with high conductivity can easily conduct electrical currents, while those with low conductivity have difficulty allowing the flow of electricity.
Why does a pineapple conduct electricity?
Biological materials, such as this one, will usually conduct electricity due to ions in the liquid. Since an ion has an electrical charge, and is relatively free to move around, it can conduct an electrical current.

Why semi conductive materials do not conduct current well and are og little value in their instrinsic state?
why semi conductive materials do not conduct current well & all of little value in their intrinsic state
Can colour pencils conduct current?
No, colored pencils typically cannot conduct current as they are made of graphite or other non-conductive materials. Conductive materials like metal are needed to allow electricity to flow through them.
Why does conduct of electricity require a cord?
Electric current is the movement of electrons. Various materials can conduct current, but the best materials are metals, because they have plenty of electrons which can move freely. Electric appliances, therefore, are provided with cords which contain metallic strands (usually copper) which carry the current.
What is the effect of temperature on an intrinsic semiconductor?
An intrinsic semiconductor is basically a pure semiconductor, though some might argue that a small amount of doping can still yield an intrinsic semiconductor. In the crystal structure of this material, there are very few electrons crossing the band gap into the conduction band, and this stuff doesn't want to conduct much current. But as temperature increases, more electron-hole pairs will appear as electrons jump that band gap and take up places in the conduction band. And if you guessed that increasing temperature will permit the intrinsic semiconductor to conduct current flow a bit better, you'd be right. The intrinsic semiconductor has a positive temperature coefficient. More heat, more conduction under the same conditions.
What do you call materials that do not conduct eletricity well?
Materials that do not conduct electricity well are called insulators. These materials have high resistance to the flow of electrical current, preventing the movement of electric charge through them. Examples of insulators include rubber, glass, and plastic.
Why do some materials conduct electricity?
For a material to conduct electricity , it has to be impure , so for example pure silicon cannot conduct electricity but Silicon chips in computers that are mixed with other things can. So the materials that conduct are charged with little particles that allow the flow of electricityBecause of electrolytes. Or because of the metal something is made of.
Is Materials that do not conduct electrical charges at all are called insulatorst?
Yes, materials that do not conduct electrical charges at all are called insulators. Insulators have high resistivity and prevent the flow of electric current. Examples of insulators include rubber, glass, and plastic.
Is a eraser a insulator or a conductor?
Conductor
Metal conduct current?
Metal conduct electricity and flow of electricity is the current.
What materials will conduct the flow of electricity?
While electricity doesn't flow, current does. Conductors are materials that allow the electrical currents to flow through them. Metals are the best conduction, such as silver and copper.
In order to conduct an electric current a substance must contain a what?
It should contain some IONS, or charged particles.
