We know that in, general, metals and superconductors, as well as plasmas and ionic solutions conduct electricity.
Of the metals, silver conducts electricity the best, although it is relatively expensive. Copper is very commonly used because it is the second most conductive metal. We know that Group 1 and Group 2 metals (the alkali and alkaline earth metals) from the Periodic Table are good conductors. Other metals and metal alloys will also conduct, such as gold, aluminum, tungsten, brass, lead, bronze, iron ferrite, meteorite, tin, steel, iron, titanium, etc. Aluminum is also often used because it is highly conductive, and it much lighter than the other highly conductive metals.
At very low temperatures (meaning the temperature of liquid nitrogen), superconductors are by far the best conductors available. These are far superior to any known metal, but, they do not conduct at anything close to room temperature. Some superconductors have zero resistance, and so there are absolutely no current or power losses as electrons move through the material.
The general idea is that any material with free electrons will be a conductor. The more free electrons, the better the conductor will be. We also know that ionic solutions will conduct electricity. Salt water is an example of this. It should be noted that these materials include those in the solid, liquid and gas phases. As a plasma (an ionized material), electrons are suddenly made available to support conduction because of the fact that electrons have been torn from their orbits to ionize the material in the plasma. There will be a few more minor inclusions, and you can find more information by using the links.
Many metals conduct electricity, as do electrolyte solutions or liquids.
Generally speaking, an insulator like wood, rubber, porcelain etc. don't conduct electricity.
Insulators
no brinjal does not conduct electricity
It does not conduct electricity
Why does CCl4 not conduct electricity?
no, bones dosnt conduct electricity
No, camphor does not conduct electricity. It is a type of organic compound, so it cannot ionize to conduct electricity.
Rubber objects do not conduct electricity, neither do they let electricity travel through them.
A hair dryer
Is the rate or capacity that objects have to conduct electricity
Insultator
When metal objects conduct electricity the electricity just passes through them, it does not remain to impart an electrical charge.
Metals which have free valence electrons conduct electricity and heat. thus they are good conductors.
Most metals are well known to be good conductors of heat. Examples of such metals are aluminum and copper. Objects that do not conduct electricity are known as insulators.
Objects that conduct electricity poorly are called poor conductors of electricity or insulators . There is a difference though. Poor conductors of electricity are capable of conduction under certain circumstances while insulators cannot conduct electricity under any condition, example ; air is a poor conductor of electricity as it cannot conduct under normal conditions but lightning is able to pass through it during a storm.
Any solid metal plus liquid mercury in their elemental form.
Rock is generally an insulator. Note that the color of a rock is usually not a good indicator of is composition of properties.
many "objects" conduct electricity. It is a matter of which "objects" or metals are more conductive than others. The metals range from Silver to Aluminum(weak conductor). Silver is a very good conductor but expensive, so people turn to copper.
