An insulator is used to isolate current carrying components from conductive non current carrying components.
Yes, any electrical conductor can serve as an electromagnetic insulator.
yes
Oxygen is considered to be a good insulator. This is a non-metallic element that can be used for insulation purposes.
energy and structure
for warmth
What are the barrier islands and what purposes do they serve?
It is an insulator. It would take many wraps to make it become a good insulator. There are much better products in the market place to use for insulation purposes which are much safer.
Glass is an insulator because it does not conduct electricity well. However, it can become slightly conductive at very high temperatures due to ionization. Overall, glass is considered a good insulator for most practical purposes.
Lots.
No
Oil is an insulator. It does not conduct electricity well due to its low electrical conductivity, which makes it a good material for insulating purposes in various applications.
Mud is a poor conductor of heat and electricity, so it can act as a basic insulator. However, its effectiveness as an insulator can vary depending on its composition and moisture content. Overall, mud is not a reliable or efficient insulator compared to materials specifically designed for insulation purposes.
