Can insulators offer resistance to the flow of electric current?
Yes, different grades of insulators can offer different levels of resistance to current flow of electrons within a closed circuit. For instance the flow of current would be different between wood and rubber, both insulators.
What are the materials that resist the flow of electric charges through them are called?
True..Materials, such as copper or aluminum, that offer low resistance to the flow of electric charge are called conductors.
Insulators offer resistance to the flow of electric current.?
Yes, different grades of insulators can offer different levels of resistance to current flow of electrons within a closed circuit. For instance the flow of current would be different between wood and rubber, both insulators.
What metal best conducts electricity?
The best conductors of electricity are superconductors; these offer zero resistance. Many materials will superconduct when sufficiently cooled - most superconductors need to be cooled to within a few degrees of absolute zero, metals including tin and aluminum will superconduct. Somewhat ironically, gold will not superconduct - gold is a very good conductor at room temperatures. In 1986, some ceramic based materials were found to superconduct at high temperatures - still around -90oC, so not all that high - but making the effect much more useful as liquid nitrogen can be used to cool the materials. The simple answer to the best METAL conductor. Silver.
Does air conduct electricity?
Yes, Air can conduct electricity. There are a lot of conditions to it. An classical example would be lightening. Where the Current, or technically, the electrons flow between the clouds to the Ground. Every elements to an extent conduct electricity, what is more important is the amount of resistance they offer to conduct electricity. But when the Voltage or the pressure for the current to flow, the resistance does break down and allows the current to flow. Search for the term called Break down voltage. Its better to read a nice article rather to look for full explaination here..
Why do you call metals as poor conductors?
Metals are poor conductors as they offer resistance to the flow of electrons however super conductors offer less or no resistance
Do conductors offer little resistance to the flow of electric current?
Yes- you have suggested a correct working definition for a conductor.
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.

What are materials that allow charges to flow through then easily called?
electric conductor They are called conductors of electricity. Electricity is the flow of charge. Solid conductors contain free electrons that carry the charge. Liquid conductors contain ions that carry the charge.
Can insulators offer resistance to the flow of electric current?
Yes, different grades of insulators can offer different levels of resistance to current flow of electrons within a closed circuit. For instance the flow of current would be different between wood and rubber, both insulators.

Do conductors offer very little resistant to the flow of electric current?
Yes- you have suggested a correct working definition for a conductor.
Why conductors offer resistance?
Yes , all conductors have some amount of resistance although it varies depending on the material that is conducting the electricity . Copper has a very low resistance, and aluminum has a slightly higher ( but still quite low ) resistance . This is why they are used as electrical conductors. Conductor resistance results in voltage drop over the conductor and power loss, manifested as heating of the conductor . Therefore , you want as low a conductor loss as is reasonably practical . The reason of resistance is that, no electron has a linear motion when an electric field is applied to it . e- move in random due to apparent collision with other e -' s. This motion is termed to as Brownian motion . The random movement however interrupts with the electric field and creates resistance sue to a negetive field generated .
What are the property of superconductor?
Super conductors are conducting materials which below a specific temperature offer zero resistance to the conduction of current : Currently, superconductivity can only be achieved at extremely low temperatures.
Can a liquid offer resistance to stress?
yes.due to the surface tension ,there is liquid offer resistance.
Birds sitting on a power line don't get shocked because there is no to ground.?
Birds are not good conductors of electricity. Their cells and tissues do not offer electrons an easier route than the copper wire they are already travelling along
Diffrence between conductor and insulator?
A conductor easily transfers energy in the form of electricity and/or heat, while an insulator does not easily transfer these types of energy.Conductors are the substances which allow the electricity to pass through them while insulators resist electricity.A conductor is something which allows electric current to flow through it freely whereas an insulator prevents any electric current flowing through it. Mainly insulators are classified as solid materials due to the fact they offer a large resistance to the flow of current however, metals are classified as conductors as they offer a small resistance to the flow of current.CONDUCTOR: those objects which can pass electricity through them is known as conductors. the conductors can pass electricity through them due to free electrons present in them. for example: iron, copper, aluminium etc.INSULATOR: those objects which can not pass electricity through them is called insulator. the insulators can't pass electricity due to less or absence of free electrons. for example paper, wood, rubber etcA conductor easily lets "something" pass, while an insultator won't. The "something" is usually either an electrical current, or heat.A conductor differes from an insulator because it offers low resistance to the flow of current while an insulator offers high resistance to the flow of current.A conductor easily transfers energy in the form of electricity and/or heat, while an insulator does not easily transfer these types of energy.CONDUCTOR: those objects which can pass electricity through them is known as conductors. the conductors can pass electricity through them due to free electrons present in them. for example: iron, copper, aluminium etc.INSULATOR: those objects which can not pass eletricity through them is called insulator. the insulators can't pass electricity due to less or absence of free electrons. for example paper, wood, rubber etcA conductor is any material that allows electricity to pass through it, an insulator is any material that doesn't allow electricity to pass through it, so in other words, an insulator is the opposite of a conductor.A material that is a good conductor of electricity has very narraw gap between its valence band and conduction band. Whereas, insulators have a large energy gap i.e, gap between its valence band its conduction band is large. Energy has to be supplied to such material if we want to make electrons in the valance band to jump over to the conduction band.conductor is a material, that can let electricity/energy flow better whereas an insulator cannot flow as quickly and better. an insulator would be rubber, cloth, glass, Styrofoam, dry wood, and etc...Conductors - Substances which allow heat energy to flow through them easily and quickly are called conductorsInsulators - substances which do not allow heat energy through them are called bad conductors or insulatorsConductors allow electricity to pass through them where as insualtors stop the current.An example of an insulator is plastic. An example of a conductor is copper (most metals are conductors).conductor has low resistance to electricity.Insulator has high resistance to electricity.Conductors conduct electricity or heat due to free electrons. In conducting heat the electrons of a conductor vibrate and affect the electrons nearby vibrate as well and thus conduct heat. Similarly, conductors have free electrons to move and thus conduct electricity.Insulators do not have free electrons and theses electrons are bound and do not freely vibrate when heated. Nor are they able to travel when an electrical current is applied.An insulator has no free non bound electrons whereas a conductor does.
