한국 과학기술인 연합 질의응답중 중간에 있음.

중.. "그러면, 이상적인 절연체나 전도체에 프로브를 대는 순간 무한대, 그리고 전도체는 0이라는 값이 측정기기에 뜨겠죠?

그러면 반도체 물질의 경우에는 어떤가요? "

Q : So with 4 probe measure, non-conductor show infinity ohm?

A : Yes, when using the 4-probe method to measure a non-conductor (insulator), the resistance value will approach infinity, or at least be extremely high compared to conductive materials. This is because non-conductors are materials that do not allow the flow of electric current.

In practical terms, the resistance measurement for a non-conductor might not be exactly infinite but rather a value that exceeds the measurement capability of the equipment being used. The measurement could also be affected by noise, environmental factors, or the presence of impurities, but the underlying characteristic would still be an extremely high resistance value.

Keep in mind that in a real-world setup, it might be challenging to ensure perfect contact with a non-conductive material, and other factors like static charge accumulation could complicate the measurement. Therefore, interpretation of the results should take into account the specific conditions of the measurement and the characteristics of the material being tested.

In summary, while a non-conductor won't necessarily show an "infinite" resistance value on your equipment, it will present a resistance that is orders of magnitude higher than what you would expect from conductive or semiconductive materials, and this is a clear indication of its insulating properties.
