What is the resistance of the air gap . |
| Answer» Air gap\xa0(networking) From Wikipedia, the free encyclopedia. An\xa0air gap,\xa0air\xa0wall or\xa0air\xa0gapping is a network security measure employed on one or more\xa0computers\xa0to ensure that a secure\xa0computer\xa0network is physically isolated from unsecured networks, such as the public Internet or an unsecured local area network.\xa0An\xa0air gap\xa0is completely insulator i.e. very high electrical\xa0resistance\xa0≈ 109\xa0Ωm, since it consists of molecules of oxygen and nitrogen. There are no free electrons. However, application of very high potential ionizes\xa0air\xa0and it becomes conducting, the potential gradient required is 3x106\xa0V/m. | |
