A conductor exhibits the following properties in equilibrium condition: A conductor always allows the movement of electrons and ions in them. The electric field of a conductor is zero allowing electrons to flow within them. The charge density of a conductor is zero.
What is a material that offers no resistance to the flow of electrons and conducts electricity?
The superconductor is a material that offers no resistance to the flow of electrons and conducts electricity. The superconductivity phenomenon was discovered by Heike Kamerlingh Onnes, the Dutch Physicist in the year 1911. Superconductors are elements or metallic alloy, when cooled below a certain threshold temperature, lose electrical resistance property and become superconductors.
What is the property of an electrical conductor?
An electrical conductor allows the electric charges to easily flow through them. The property of conductors to “conduct” electricity is called conductivity. Such materials offer less opposition or “ resistance ” to the flow of charges.
What is the meaning of conductors?
If you have to define the meaning of electrical conductors in the simplest way, they are materials that allow electricity to flow through them easily. If we compare two types of material and the first one allows better flow of electricity through it, then that material is said to be a good conductor of electricity.

What are conductors used for?
12 Uses of Conductors in Daily Life – Types. Conductors are elements that conduct heat quickly and also can cool things quickly such as in wire coil in the back of refrigerator. It has function to conduct the heat of refrigerator to the air around refrigerator. Kitchen closely related with our skin’s heat if we can not stand the heat.
What are the best spark plugs made of?
In the auto parts industry, the benefits of silver are used in the manufacture of spark plugs. Spark plugs on the vehicle play an important role in supporting the engine heating perfectly. In this case, the best spark plugs for motor vehicles are spark plugs made of silver .
What is copper wire?
Copper is a pure metal that has a high electrical conductivity that is about 57 S. Copper works on the conductor cable. Cable that uses copper is wired cable, coaxial cable, NYA, NYAF and etc. Wired cables: high-circular electric wires surrounded by insulation. Coaxial cable: electric cable made of fine copper.
Is copper a good conductor?
Copper (Cu) is a good heat conductor but has a high corrosion rate. Its color is reddish orange and has soft character with a boiling point of 2835 °K (2562 °C, 4643 °F). Therefore it is utilized for electrical conductor in the form of isolated cable. If it mixed with lead will produce bronze.
Is silver wire better than copper wire?
Silver wire is worth selling higher than copper wire. Fair enough, considering the quality is also better. Silver wire will be packed and used as cables for various electronic devices. Starting from the power cable, audio connector cable, even the cable used for high quality loudspeakers.
Does gold have good conductivity?
Although gold reacts chemically by free chlorine, good conductivity and general resistance to oxidation and corrosion in other environments (including resistance to nonchlorinated acids) has led to the industry being used extensively in the electronic age as a thin layer of electrical connectors of all kinds, ensuring good connection.
What is a conductor?
Conductors are materials with low resistivity (or high conductivity) that allow the flow of electric charges. Commonly, resistance (conductance) of a conductor increases (decreases) under strain due to the appearance of cracks in conductive paths.
What is metallic conductor film?
Metallic electrical conductor films are widely used in the hybrid microelectronics and semiconductor industry, where thin film “blanket metallization,” which covers the whole surface, is chemically etched or plasma etched into conductor patterns. The thin film material can also be deposited through a physical mask to form a conductor pattern on the surface. Masking techniques are useful on conductor geometries down to about 2–5 microns in width and have the advantage that they do not have to be chemically etched.
How do ferromagnetic conductors heat up?
Ferromagnetic conductors can be rapidly heated by interaction with a high frequency (radio frequency, RF) electromagnetic field. The sample to be pyrolyzed can be placed in close contact with the conductor, which can be shaped into different forms such as a wire, ribbon, folded ribbon or cylinder to properly hold the sample. The sample and its holder are maintained in a stream of inert gas in a similar way as for resistively heated filaments. The housing where the sample and its ferromagnetic holder are introduced is also heated to avoid the condensation of the pyrolysate but without decomposing the sample before pyrolysis. The heating of the conductor and subsequently of the sample can be realised with a short TRt, commonly between 10 and 100 ms. Eddy currents in the conductor surface (skin) and hysteresis losses due to changes in the magnetic polarity cause the temperature to increase rapidly when the conductor is placed in the high frequency electromagnetic field. The increase in temperature is, however, limited for these ferromagnetic conductors to the Curie point temperature [24]. This is a temperature specific for each material where the transition from ferromagnetic to paramagnetic properties occurs. In this way, besides a rapid heating, a well-defined end temperature is attained. This end temperature (Curie point) depends on the composition of the ferromagnetic metal or alloy, and lists of Curie point temperatures for various alloys are available in literature [25] or provided by the instrument manufacturers (e.g. Ref. [26] ). The temperatures obtained with Curie point instruments cannot be varied continuously and are set by the choice of the alloy type of the heating element. Several Curie point temperatures generated by different ferromagnetic alloys are indicated in Table 2.2.1.
How does temperature rise depend on the mass of a conductor?
This power consumption per unit surface is related to the amount of heat generated by the conductor and implicitly to the temperature.
What is the term for the strength of a magnetic field?
The term magnetic field strength is used to describe the power of the field in a vacuum, the term magnetic flux to describe the field which results when a magnetic field is present in any material and, as noted above, this may be greater than the original magnetic field strength.
What is the region throughout which a magnet or a current-carrying conductor exerts its effects?
The region throughout which a magnet or a current-carrying conductor exerts its effects is known as a magnetic field, and a changing magnetic field induces a flow of electrons in a conductor to produce an electric current.
What is the property of a conductor that can exert a force on another conductor carrying a current?
A conductor with a current flowing through it can exert a force on another conductor carrying a current; this is the property known as magnetism . Some substances, e.g. iron alloys, can exhibit magnetism although it appears that no current is flowing through them. In this case, the magnetism is due to the sum of the many minute currents formed by the motion of electrons orbiting their nuclei.
Conductors vs. Insulators
10 Electrical Conductors
- The best electrical conductor, under conditions of ordinary temperature and pressure, is the metallic element silver. Silver is not always an ideal choice as a material, however, because it is expensive and susceptible to tarnishing, and the oxide layer known as tarnish is not conductive. Similarly, rust, verdigris, and other oxide layers reduce co...
10 Electrical Insulators
- Electric charges do not flow freely through insulators. This is an ideal quality in many cases—strong insulators are often used to coat or provide a barrier between conductors to keep electric currents under control. This can be seen in rubber-coated wires and cables. The most effective electrical insulators are: 1. Rubber 2. Glass 3. Pure water 4. Oil 5. Air 6. Diamond 7. Dry …
Other Factors That Influence Conductivity
- The shape and size of a material affect its conductivity. For example, a thick piece of matter will conduct better than a thin piece of the same size and length. If you have two pieces of a material of the same thickness but one is shorter than the other, the shorter one will conduct better because the shorter piece has less resistance, in much the same way that it's easier to force wat…
