The reason is that there must be free electrons or charged particals that can move under the influence of an applied electric firld. Please note that other substances may conduct electricity e.g. graphite and molten ionic salts.

What can conduct electricity?

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 electronswill 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.


What are made up of free electrons and ions?

Plasmas are made up of free electrons and ions. Plasma is the fourth state of matter and it is characterized by its ability to conduct electricity. It is commonly found in stars, flames, and certain types of lighting.


Classification of plasma proteins?

There are a large number of plasma classifications. These include cold, hot and warm plasmas, plasma ionization, collisional plasmas, neutral plasmas, plasma densities, magnetic plasmas, complex plasmas, active and passive plasmas, ideal and non ideal plasmas and high energy density plasmas.


Are three states of matter?

There are now five states of matter which are the BE Condensate, solids, liquids, gases, and plasmas.


Do Plasma's have a net negative charge?

No. Plasmas are generally neutral just like other states of matter.

What properties do plasmas have that solids liquids and gases dont?

A plasma is an ionized gas ... thus its properties are those of a gas PLUS the fact that it can conduct electricity.

Unlike a gas plasma conduct electric current?

A gas plasma is a ionized gas in which atoms have lost or gained electrons, allowing it to conduct electricity. This is in contrast to a regular gas, where the atoms remain electrically neutral and do not conduct electricity well.


What has no definite shape volume and conducts electricity?

A plasma is a state of matter that has no definite shape or volume and can conduct electricity. Plasmas are made up of charged particles that can move freely and interact with electric and magnetic fields. Examples include lightning and some types of gas discharges.

When was Physics of Plasmas created?

Physics of Plasmas was created in 1994.


Does plasmas have an indefinite shape?

Plasmas do not a have a fixed shape.


Do plasmas have a definite volume?

No. Plasmas are ionized gas.


Why do people throw away good plasmas?

plasmas break easily


The future of plasma in electronics field?

Plasmas are conductive assemblies of charged particles, neutrals and fields that exhibit collective effects. Further, plasmas carry electrical currents and generate magnetic fields. Plasmas are the most common form of matter, comprising more than 99% of the visible universe, and permeate the solar system, interstellar and intergalactic environments. When considered inclusively, it is clear that plasma science and technology encompasses immense diversity, pervasiveness and potential. The future is right for the this plasma features: Plasmas for Home, Business and Transportation Plasmas for Space Plasmas and Manufacturing Plasmas for Energy Plasmas for National Security Plasmas for the Environment Plasmas and Education


Is dry wood a good conductor?

No, dry wood is not a good conductor of electricity as it has high resistance. This is because it contains very few free ions or electrons to carry electric current. Wet wood, on the other hand, can conduct electricity better due to the presence of moisture.
