If we speak in terms of electrical conductivity, some good insulators are ceramics, plastics, rubber and glass. Conductors are, on the other hand, metals in general: copper, silver, gold, but there are some good conductors that are not metals, like graphite and some salt solutions.
An examle of a conductor are any metal and an insulator is wood and even your winter coat! insulator is a open circuit
Earth, human body and metals are conductors of electricity
Ebonite, rubber, porcelain, glass, mica, plastic are good insulators.
Note, that human skin is a fairly good insulator, while under the skin, the human is a pretty good conductor. The best insulator is space.
An insulator would be something that prevents the flow of electrical current. An example would be rubber.
A conductor would be something that allows the flow of current. For example, electrical wire (normally copper or almn)
i'll just give you as many as i can. conductor: copper, gold, iron, steel, brass, bronze, concrete, metal, and coins. insulator: rubber, plastic, glass, dry wood, procelain, cloth, paper, styrofaom, plants, and pure water.
* Insulator (electrical), a substance that resists the flow of electric current * Insulator (genetics), an element in the genetic code * Thermal insulation, a material used to resist the flow of heat * Building insulation, a material used in building construction to prevent heat loss * A Mott insulator, a type of electrical insulator * Electrical conductor, a material allowing the flow of electric current * Electrical conduction, the movement of charged particles through an electrical conductor
Most metals are conductors. Salt water is also a conductor.
Most plastics, rubber, and dry wood are insulators. Dry air is an insulator, but can become ionized.
A copper wire is an electrical conductor. The plastic coating covering the copper wire is an insulator.

260 pounds for the tank plus about 400 pounds of propane. 660 pounds total.
That depends on the specific material of the insulator versus the specific material of the metal. But the answer is easily in the millions. This is your lucky day! Just for you, today, we're having a special. I went and found a list with actual numbers and everything, and I compared glass with copper. Depending on the composition of the glass, the ratio of resistivities is between 5.95 billion billion and 5.85 thousand billion billion. I have to thank you for posting this question, because I've never looked at a list of these before, and I found some more interesting comparisons. (The actual numbers are down at the bottom.) -- Silver, the best conductor by just a bit, has 5.4% less resistivity than copper. -- Gold . . . 45.2% greater resistivity than copper -- Iron . . . 4.1 times the resistivity of Gold, 6.0 times that of Copper -- Lead . . . 2.2 times the resistivity of Iron, 13.1 times that of Copper -- Nichrome, the resistor wire used for the heating coil in a toaster . . . 5 times the resistivity of Lead, 65.5 times that of Copper -- Teflon . . . 1 billion to 10 thousand billion times the resistivity of Glass, 5.95 million trillion trillion to 5.95 hundred million trillion trillion times that of Copper ==================================== Silver. . . . . 1.59 x 10-8 ohm-meter Copper . . . 1.68 x 10-8 Gold. . . . . . 2.44 x 10-8 Iron . . . . . . 1.0 x 10-7 Lead . . . . . 2.2 x 10-7 Nichrome . . 1.1 x 10-6 Glass . . . . . 1011 to 1014 Teflon. . . . . 1023 to 1025
As of 2010, the Bose-Einstein condensate state of matter has only been achieved in temperatures of 10-7 K in many alkali and alkaline earth metals' isotopes. They include: 7Li, 23Na, 39K, 41K, 85Rb, 87Rb, 133Cs, 52Cr, 40Ca, 84Sr, 86Sr, 88Sr, and 174Yb

A coax cable has a center conductor surrounded by an insulator and then a metal braid. You are likely referring to the braid.
Give atleast two examples in sentence form of each of the 7 Cs?
no...i really dont know
No,it doesn't.Let me give you some examples. 7-3=4 =7+(-3)=4
x = 1/2. y = -3/7.
hey bay you may say that you need some hay.
1 10,000 1/3 22/7 792/793
Prime numbers like 2, 3, 5 and 7
-3 to -7 c
The absolute value of +7 (positive 7) is 7 (positive 7). The absolute value of -7 (negative 7) is 7 (positive 7). The absolute value of 0 (zero) is 0. Generally, negatives become positives and positives retain their sign.
1. Oven mitt 2. wool coat 3. non metallic objects 4. wood 5. plastic 6. glass (insulates electricity) 7. clothes 8. paper 9. rubber 10. pure water
LCM of 4 and 5 is 20 LCM of 6 and 3 is 6 LCM of 5 and 7 is 35
