Myella! A conductor is made up of rubber, copper, silver, gold, aluminum, etc. This answer is if you are talking about electricity. If you are talking about Biology, I have no idea. Sorry if you did want biology... hehehehe.
A conductor of heat if it is made of metal.
Combs are made of plastic, and plastic is not a great conductor of electricity.
It depends on what it's made of. A metal is a conductor and a nonmetal is an insulator.
It's made of metal and metal is a conductor of electricity.
Copper is an excellent conductor of electricity, and so can safely conduct away the charge of a lighning bolt without heating up and creating a fire hazard. The only better conductor is silver, which is too expensive for such a use.
plastic is a bad conductor of heat because it is made up of different man made material's.
Diamonds are an excellent conductor because they are made up of tightly packed carbon atoms.
It's made of steel with a coating of nickel, so it is a conductor but not as good as the old coins with copper in.
The material from which the conductor is made, the length of the conductor, the diameter of the conductor and the temperature of the conductor are all things that impact its resistance.
A key would be a conductor. ------------------------------------------------------ That would depend on what the key was made of. Keys made out of metals would be conductors, while contactless plastic car keys would be insulators.
Most are currently made of copper. In the past, some were made of silver and even gold. Silver is a better conductor than copper, and gold is a better conductor than silver. As you can imagine, both are rather cost prohibitive.
A conductor of heat if it is made of metal.
Depends on the material, not the item. Metals are conductors, so a metal screwdriver blade Will be a conductor.
Combs are made of plastic, and plastic is not a great conductor of electricity.
It depends of what it is made of. Leather beach ball is not a conductor.
they are usually made of copper or aluminuim
Conduction or insulation depends on material, not shape or purpose. A metal blade is a conductor.
