Question Why Is Silicon A Poor Electrical Conductor 2

Is silicone bad conductor of electricity Note Pure silicon are weak conductors of electricity because their outer electrons are bound together in the covalent bonds of the diamond frame Electrical conductivity decreases as the temperature of the metals increases since the motions of the atoms make the passage of electrons more difficult.

Band Theory of Electrical Conductivity

In describing conductors using the concept of band theory it is best to focus on conductors that conduct electricity using mobile electrons According to band theory a conductor is simply a material that has its valence band and conduction band overlapping allowing electrons to flow through the material with minimal applied voltage.

Liquids conduct electricity

20 03 2019  The materials which allows electric current to pass through them easily are called good conductors of electricity. The material which do not allow electric current to pass through them easily are called poor conductor of electricity. The metal such as copper and aluminium allow electricity to pass through them easily so they are good conductors of electricity.
