Nettet16. sep. 2024 · Insulators In contrast to metals, electrical insulators are materials that conduct electricity poorly because their valence bands are full. The energy gap between the highest filled levels and the lowest empty levels is so large that the empty levels are inaccessible: thermal energy cannot excite an electron from a filled level to an empty one. NettetAnswer: Insulators are used in making switchboard, handles of testers, screw drivers. 8. What is the name of thin wire in the electric bulb? Answer: Filament. 9. In which of the following circuits A, B and C given below, the cell will be used up very rapidly? Answer: I circuit A the cell will get used up rapidly. 10.

The energy gap of AlP is Eg = 2.45eV, so it is a semiconductor [9] [10, p. 432,543]. If a beam of light with … NettetConductors allow for charge transfer through the free movement of electrons. In contrast to conductors, insulators are materials that impede the free flow of electrons from atom to atom and molecule to molecule. If charge is transferred to an insulator at a given location, the excess charge will remain at the initial location of charging. raji raj minerals pvt ltd
