Is the eraser a conductor or insulator?
A magic one is an insulator.
Why is metal not a good insulator of electricity?
Silver is part of the metal group on the Periodic table of elements and metals are good conductors of heat and electricity so silver would be a good conductor and insulator.
Why Styrofoam can be a best insulator?
It's not metal or copper like wires. Metal is an easy conductor of heat. Styrofoam isn't. Therefore making it an insulator. Answered by a fifth grade student
How do you convert conductivity to resistivity?
Conductivity is a measure of the ability of a substance to conduct electricity. Resistivity is a measure of how strongly a substance resists the flow of an electric current. So conductivity and resistivity are opposed to each other. A good conductor like copper has a low resistivity, and a good insulator like glass has a low conductivity and a high resistivity. Mathematically, conductivity and resistivity are inverses of each other, so it is quite easy to convert conductivity to resistance.
What makes wood a good insulator?
Electrical current is the movement of free electrons. A free electron is one that has been forced lose of it's orbit and is drifting between the other atoms. If you were to put a peace of metal between the terminals of a car battery it would conduct a a lot of current, but a peace of wood, hardly any, if any at all, the reason being, the electrons are not so easy to force out of they're orbits as the metal, so wood makes a good insulator because it is not a good conducter of electrical current, or it is, on a common scale adverse to the movement of free electrons.

What a conductor is and what an insulator is?
A conductor allows energy (such as electricity or heat) to pass through it with little resistance or impediment. Copper is a good example, as it is very good at transferring both types of energy: which is why it's used for both cooking pots and electrical wiring. An insulator blocks or slows down the transfer of energy. An electrical insulator such as the plastic covering used in electric cords, for instance, allows you to handle the plug without getting electrocuted by the current. And an ice chest or cooler blocks warm air from getting inside the container, giving you an easy way to bring ice cold beer to the beach or on a picnic.
Why consumer wants connect to high voltage?
that main resign is high voltage is voltage value is high that same time current value is very low. easy to transmission to long distance consumer(HT required consumer) end we have not voltage loss and current also and conductor cost is reduced that is conductor thickness low ,so current level is low
Why is it difficult to charge a metallic conductor which is held with the hands why is it easy charged a non conductor although it is held by the hands?
why is it difficult to charge a metallic conductor which is held with the hands ?why is it easy charged a non conductor although it is held by hte hands
Explain why the outside cases of electric appliances ususally are made of plastic?
Plastic is a good insulator and a bad conductor of electricity, which makes it a good material to protect people from electric shocks when handling appliances. On top of that, plastics are inexpensive and easy to shape.
Compare conductor and insulator?
Conductors and insulators are different and simalar in many ways.Two ways they are simallar are they both have electrons and have something to do with electricity.Three ways they are different that conductors let heat and electricity go through it .On the other hand insulators do not let heat or electreicity go through it easily.Another way is conductors transfer eelectrons easily but meanwhile the insulator psses on electrons with difficulty.One last thing is that conductors are not current but insulators are current.

Copper is used to make electric wire because it is a good insulator?
You are confusing an insulator with a conductor. An insulator prevents passage of electricity (in this case) from one point to another whilst a conductor allows passage. Copper is an excellent CONDUCTOR of both heat and electricity which is why it is used in wire. It also has some other good properties which enhance it's suitability-plentiful, reasonably cheap, easy to work (i e in this case to manufacture into wire) and reasonably lightweight. Other metals such as Gold and Silver are better conductors of electricity but their cost is huge in comparison and are softer and less durable making them uneconomic for all but exotic applications such as very high end Audio Interconnects and/or Speaker Cable, Microchips etc.
Why is NaCl and KI a conductor of electricity?
In dry or crystalline form, salt (Sodium Chloride) is a poor conductor. But when it is dissolved in water, the sodium forms Na+ ions and the Chlorine forms Cl- ions. With these extra ions in the water, it is easy for electrons to be carried through the solution and current to flow.
Is copper the best conductor?
because copper atom has one electron in outer shell and easy to to energize to flow to other copper atom we now that the rate of flow of electron is current
What is a substance that allows easy transfer of energy called?
A conductor allows easy transfer of energy.
