Metals are the most common type of conductors. In metals, the outermost electrons, known as "free electrons," are not tightly bound to the atomic nuclei and are capable of moving through the material when a voltage is applied. This is why metals are excellent conductors of electricity.
Copper and aluminum are two of the most widely used conductors due to their high electrical conductivity and other desirable properties. Other materials, such as water with dissolved ions, certain types of graphite, and various alloys, can also act as conductors to varying degrees.
Conductors play a vital role in electrical and electronic circuits, as they enable the flow of electric current, facilitating the transmission of power and signals.

Conductor. It can be referred to as Electrolytic conductor as well if a fluid is used to create a potential difference between two points.

What makes a good electrical conductor?
number of electrons capable of freely moving in the outermost shell of an element. eg. Copper
Junction field effect transistor biasing?
When the gate is forward biased, the depletion region is lesser and so the majority carriers(electrons)move freely towards the drain from the source producing high output impedance.When the gate is reverse biased,the depletion region increases(especially near the drain forming wedge shaped depletion)and thus the free flow of the electrons is opposed.hence the output current decreases.The out current becomes zero if the voltage given to the gate is maximum.
What technologies uses solar cells to produce electricity?
Basicaly in solar cells the photons are converted to electrons . The solar cells that you see on calculators and satellites are also called photovoltaic (PV) cells, which as the name implies (photo meaning "light" and voltaic meaning "electricity"), convert sunlight directly into electricity. A module is a group of cells connected electrically and packaged into a frame (more commonly known as a solar panel), which can then be grouped into larger solar arrays, like the one operating at Nellis Air Force Base in Nevada. Photovoltaic cells are made of special materials called semiconductors such as silicon, which is currently used most commonly. Basically, when light strikes the cell, a certain portion of it is absorbed within the semiconductor material. This means that the energy of the absorbed light is transferred to the semiconductor. The energy knocks electrons loose, allowing them to flow freely. PV cells also all have one or more electric field that acts to force electrons freed by light absorption to flow in a certain direction. This flow of electrons is a current, and by placing metal contacts on the top and bottom of the PV cell, we can draw that current off for external use, say, to power a calculator. This current, together with the cell's voltage (which is a result of its built-in electric field or fields), defines the power (or wattage) that the solar cell can produce. That's the basic process, but there's really much more to it. On the next page, let's take a deeper look into one example of a PV cell: the single-crystal silicon cell.
When light strikes a photocell does the resistance increase or decrease?
When light strikes a photocell, the resistance decreases, allowing current to flow more freely.
Which metal is used for electrical contacts?
Copper is used the majority of the time. Gold is sometimes because it does not corrode. Tungsten is used in light bulbs because it is a good resistor and resists the flow of electrons. Aluminum and silver are also sometimes used. There is also some recent research in safely using sodium and lithium.
What type of material allows electrons to move freely?
Electrons move freely in a solid, as in a metal
What is the material which allows electrons to freely pass from one atom to another?
A Conductor :)
A material that prevents electrons from flowing freely is called what?
an insulator
What materials allow electricity to flow freely?
Because of freely moving of electrons in the material
What do you call a material that electrons will flow through freely?
conductor
What are electrons that do not move freely called?
protons????
Materials that allow the charges of an electric current to move freely through them are called what?
A materiel that allows an electric charge to pass through it is an conducter (copper, for example)
Why do wires use metals?
The purpose of a wire is to carry some sort of electrical signal. This requires that the electrons in the material be able to move freely. Materials with free movable electrons are called "metals".
Is a material a good insulator if outer electrons of atoms in the material are free to roam around?
Freely moving electrons make materials more conductive, and less insulating.
Why does metal conduct electricity?
metal conducts electricity because it allows electrons to move freely as well as it has free electrons, unlike insulators(non-metals) which do not have free electrons. When the electrons are allowed to move freely in a substance, it is a good conductor and allows electric charge to flow.
What allows a conductor to conduct electricity?
Conductors are substances where electrons can freely move from atom to atom.
What name do you give to materials that let eletricity pass through them easily And why?
The material is conductive. Metals (copper or aluminum, etc) allows charged particles of electrons to move freely in either direction along their length.
