Difference Between Conductor, Insulator and Semiconductor
The major difference between conductor, insulator and semiconductor is defined by the flow of charged particles under the influence of electric field. When any voltage is applied to the conductor, electric charged particles easily flow from valence band to conduction band. Thus conductor is a good conductor of electricity. A semiconductor allows very low charge particles to move from valence band to conduction band. In insulators, there is no flow of charge particles under the influence of electric field hence insulators are the bad conductor of electricity.

An electrical conductor is a substance in which electrical charge carriers, usually electrons, move easily from atom to atom with the application of voltage. Conductivity, in general, is the capacity to transmit something, such as electricity or heat.
Pure elemental silver is the best electrical conductor encountered in everyday life. Copper, steel, gold, aluminum, and brass are also good conductors. In electrical and electronic systems, all conductors comprise solid metals molded into wires or etched onto circuit boards.
Some liquids are good electrical conductors. Mercury is an excellent example. A saturated salt-water solution acts as a fair conductor. Gases are normally poor conductors because the atoms are too far apart to allow a free exchange of electrons. However, if a sample of gas contains a significant number of ions, it can act as a fair conductor.
