5. 
   Insulator
   A material which does not usually conduct electricity. Air, for example is an insulator. Insulators have a very high (ideally infinite) resistance. Given a suitably high voltage, insulators can be forced to conduct - take for example lightning during a thunderstorm. See also conductors and semi-conductors

7. 
   Insulator
   A material that does not allow the passage of electric charge or is a poor conductor of thermal energy. Ceramics are good insulators. A nonmetallic material that has filled valence band at 0 K and a relatively wide energy band gap.

9. 
   insulator
   Insulator is a material in which the highest occupied energy band (valence band) is completely filled with electrons, while the next higher band (conduction band) is empty. Solids with an energy gap of 5 eV or more are generally considered as insulators at room temperature. Their conductivity is less than 10-6 S/m and increases with temperature.

11. 
    Insulator
    A material which strongly resists the flow of electrons through it. The rubber on an electrical cord provides an insulator for the wires. By covering the wires, the electricity cannot go through the rubber and is forced to follow the path of the wires.

12. 
    Insulator
    An object or material that, by the property of high resistance, insulates the surround material from usually high voltage electricity. In more general terms, a non-conductor of electricity, sound or heat.

17. 
    Insulator
    An `insulator` is a genetic boundary element that plays two distinct roles in gene expression, either as an enhancer-blocking element, or more rarely as a barrier against condensed chromatin proteins spreading onto active chromatin. The need for them arises where two adjacent genes on a chromosome have very different transcription patterns, and it is critical that the inducing or repressing mechanisms of one do not interfere with the neighbouring...
