some semiconductors have comparatively low resistivity, and this is due to their containing electrically active impurities with energy-levels near a band edge. Others have very high resistivity and this is due to their containing a predominance of impurities with levels far from the band edges, that is, far compared with the thermal energy kT. These latter materials are often referred to as insulators, but since they can carry electronic currents we prefer to introduce the term 'semi-insulator' to describe them.
an insulator doesn't allows electricity pass from it, a bad conductor allows electricity to pass from it but not fully or completely and a semi conductor pass electricity in little form which used to operate electronics
Lead is a metal and is considered a good conductor of electricity. It is not a semiconductor or insulator.
semi conductor
No, Perspex is not a semiconductor. It is a type of transparent plastic material known as polymethyl methacrylate (PMMA). Semiconductors are materials that have conductivity between that of a conductor and an insulator.
Glass is an insulator. It does not conduct electricity because its structure lacks free electrons that can move easily to carry an electric current.
Copper is a conductor.
No, sodium is a metal and is not a semiconductor. Semiconductors are materials that have conductivity between that of a conductor and an insulator. Sodium is a good conductor of electricity due to its metallic properties.
Conductor-one which conducts(allow current)electric city in all condition. Semiconductor-One which behaves like conductor as well as insulator depending on condition. Insulator-one which donot conduct(allow current)electric city in all condition

A semi conductor is not a good conductor or a good insulator.

Electronics refers to anything that requires electricity to run. A semi conductor is a material that has some properties of a conductor, meaning it allows electricity to flow through it well and some properties of an insulator, meaning it does not allow the flow of electricity through it well. Semi conductors are used extensivly in modern electronics and circuit boards. the queastion makes no sense - check what you are asking
Most conductors conduct both heat and electricity well. A semiconductor is a conductor whose resistance is between that of a conductor and an insulator. An example of a semiconductor is silicon which is used in electronic appliances
Glass is an insulator. It does not conduct electricity because its structure lacks free electrons that can move easily to carry an electric current.
Semi-conductor is a material in which the energy band gap between the conduction band and valance energy band is very less (around 1V) which is in between conductors and insulators So, with just a an excitation energy of around 1v changes the state of semi-conductor to wither conductor or insulator .
