Conductor - Low resistance to the flow of electricity,heat or other form of energy Insulator - High resistance to the flow ofelectricity, heat or other form of energy
Resistors and conductors are actually two sides of the same story. They both conduct electricity and they both resist conducting electricity. The difference is how well they conduct electricity. Copper, Silver and Aluminum are examples of brilliant conductors. They resist very little. Coal-…fibers and various metal oxides are examples of poor conductors. They resist much more and falls into the category of being a resistor. The comparison can easily be made with a water pipe-line. A huge dimension can carry a lot of water (This is electrical current). It can also contain high pressure (In this analogy, that would be Voltage) A very small dimension can not carry much water at all (The current is limited. This is what physically happens in a resistor.) The water pressure is the same, then the big pipe might fill a bathtub in 30 seconds where as the small pipe would maybe need 10 minutes or more. It works "exactly" the same way with electric components as conductors and resistors. Some people claim that a conductor is the opposite of a resistor. This is a wrongful interpretation although it seems to make sense... They are both conductors of voltage (water pressure as an analogy). A resistor only limits the current, Amount of water in previous analogy, somewhat, this depending on the specifications of the resistor. A conductor is a good leader of the electricity and a resistor is damping the electricity. ( Full Answer )
A conductor easily transfers energy in the form of electricityand/or heat, while an insulator does not easily transfer thesetypes of energy. Conductors are the substances which allow the electricity to passthrough them while insulators resist electricity. A conductor is something which allows elect…ric current to flowthrough it freely whereas an insulator prevents any electriccurrent flowing through it. Mainly insulators are classified assolid materials due to the fact they offer a large resistance tothe flow of current however, metals are classified as conductors asthey offer a small resistance to the flow of current. CONDUCTOR : those objects which can pass electricity throughthem is known as conductors. the conductors can pass electricitythrough them due to free electrons present in them. for example:iron, copper, aluminium etc. INSULATOR : those objects which can not pass electricitythrough them is called insulator. the insulators can't passelectricity due to less or absence of free electrons. for examplepaper, wood, rubber etc A conductor easily lets "something" pass, while an insultatorwon't. The "something" is usually either an electrical current, orheat. A conductor differes from an insulator because it offers lowresistance to the flow of current while an insulator offers highresistance to the flow of current. A conductor easily transfers energy in the form of electricityand/or heat, while an insulator does not easily transfer thesetypes of energy. CONDUCTOR: those objects which can pass electricity through them isknown as conductors. the conductors can pass electricity throughthem due to free electrons present in them. for example: iron,copper, aluminium etc. INSULATOR: those objects which can not pass eletricity through themis called insulator. the insulators can't pass electricity due toless or absence of free electrons. for example paper, wood, rubberetc A conductor is any material that allows electricity topass through it , an insulator is any material thatdoesn't allow electricity to pass through it , so in otherwords, an insulator is the opposite of a conductor . A material that is a good conductor of electricity has very narrawgap between its valence band and conduction band. Whereas,insulators have a large energy gap i.e, gap between its valenceband its conduction band is large. Energy has to be supplied tosuch material if we want to make electrons in the valance band tojump over to the conduction band. conductor is a material, that can let electricity/energy flowbetter whereas an insulator cannot flow as quickly and better. aninsulator would be rubber, cloth, glass, Styrofoam, dry wood, andetc... Conductors - Substances which allow heat energy to flow throughthem easily and quickly are called conductors Insulators - substances which do not allow heat energy through themare called bad conductors or insulators Conductors 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. ( Full Answer )
A conductor allows electrons to flow through it when voltage(electicity) is applied to it. A non conductor or insulator as it should be known does the reverse
An insulator resists the movement of energy (heat or electrical,for example) while a conductor permits energy such as heat orelectricity to move with relative efficiency.
The difference between a conductor and a insulator is that a conductor tries to keep the warmness away and the insulator tries to keep the warmness in. An insulator is like an refrigerator, and mabey a cooler so when you go hiking it keeps the coolness inside or keeps the warmness inside!!:-)
Insulator do not have free electron and very high energy gap. conductor have free electron .

Conductor are materials which electric current can flow freely, and Insulator are materials which electric current cannot flow freely. Metals such as copper typify conductors, while most non-metallic solids are said to be good insulators, having extremely high resistance to the flow of charge throug…h them. "Conductor" implies that the outer electrons of the atoms are loosely bound and free to move through the material. Most atoms hold on to their electrons tightly and are insulators. In copper, the valence electrons are essentially free and strongly repel each other. Any external influence which moves one of them will cause a repulsion of other electrons which propagates, "domino fashion" through the conductor. Simply stated, most metals are good electrical conductors, most nonmetals are not. ( Full Answer )
A conuctor conducts electricity e.g.copper whilst an insulator does not allow electricity to go through e.g. plastic
A semiconductor is a device which is neither a Insulator nor aconductor. They behave like one in the right conditions.
SemiConductor = Kind-of-conducts. Really! By applying electricity to the conducting material (usually in a transistor or Integrated chip) the conduction rate of the material changes. This allows you to change the flow of electricity through the semiconductor by using a second smaller control voltag…e. This is the basis of most electrical components. Conductors . (made out of materials that are not semi-conductors) fully allow electricity to flow through it. Insulators (Non-Conductors) . completely block the flow of electricity. ( Full Answer )
Diodes are mainly made up of silicon like semiconductors. It has acrystalline structure. Different types of diodes are available. Forexample pn junction, zener, point contact, tunnel, photo diode,LED, shockley, etc. When silicon is there it has 4 electrons in thevalence shell and is bonded with 4 el…ectrons of adjacent siliconatoms. By doping, that is adding impurities (group 13 or group 15)elements, we can increase the conductivity of a semiconductor byintroducing p and n regions which shows holes and electrons werethe majority charge carriers. The semiconductor used in very early crystal diodes used asdetectors in radios was galena (lead sulphide crystal) and used astiff sharply pointed "cat's whisker" point contact. Naturallypresent impurities in the galena made doping unnecessary. During WW2 germanium crystal point contact diodes were introducedfor use in military radios. Naturally present impurities in thegermanium made doping unnecessary. Germanium junction diodes were introduced in the early 1950s (alongwith germanium junction transistors), silicon junction diodes andtransistors were introduced in the late 1950s and took most of themarket in the early 1960s.

This question can apply to either electricity (electron flow) or heat (thermal energy transfer). Let us start with electricity: An insulator exposed to a voltage will not let electrons flow (will not let current flow) until a very high voltage is applied, at which point the insulator breaks down …(changes composition) and allows a current arc. A conductor exposed to a voltage will allow electrons to flow and the current flow will be roughly proportional to the applied voltage. Now, let us go to heat: An insulator resists the transfer of molecular vibration energy, but what energy is transferred is roughly proportional to the temperature differential. A conductor allows the transfer of molecular vibration energy and the transfer is roughly proportional to the temperature differential. ( Full Answer )
Conductors conduct electricity or heat, energy a Dielectric is essentially an insulator.This has nothing to do with juvenile literature. by the way, waxed paper has a Dielectric of 540,00 Volts per Cubic centimeter, as determined by l909 engineering manuals. I will not reveal how I learned that!

A conductor is just that - something that conducts electric current. A semiconductor, however, is a material that can be and is used because by doing some things to it, we can cause its resistance to vary dramatically over a fairly wide range of values. We can cause it to conduct with little resista…nce, and we can cause it to resist current flow completely and prevent current from flowing. The material is a semi conductor, and it "sort of" conducts - either well or poorly or something in between, depending on how the device is made and on what we tell it to do.. Conductor will pass electrons by the laws of electrical conductivity. Semiconductor will pass electrons basically only one way. . Conductors, like copper, are materials that simply conduct electricity from point A, such as the negative terminal of a battery, to point B. Semiconductors are materials that conduct electricity from point A to point B, but have high high resistance. Many conductors can be modified to have unique properties when electricity is applied, such as in transistors. Put simply, semiconductors have an electrical conductivity somewhere between that of conductors (gold, copper) and insulators (wood, rubber). A conductor allows an electric current to flow through it equally well in either direction. The amount of current which flows depends only on the amount of resistance of the conductor and on the amount of voltage applied across it. The direction of flow can always be considered as being from the positive to the negative pole of the source of the voltage applied, so the direction of flow through a conductor is always determined by which end of the conductor is connected to the positive pole of the source.. A semiconductor allows an electric current to flow very strongly in one direction (this is known as the forward current) and very weakly in the opposite direction (which is known as the reverse current). The amounts of current which flow in each direction depend partly on the amount of the voltage applied but mainly on the forward resistance (which is relatively low) and the reverse resistance (which is always very high). So, unlike a conductor, the flow of current through a semiconductor is not the same amount of current whichever way the voltage is applied. The direction in which a semiconductor allows the forward current to flow depends on whether it is a p -type semiconductor or an n -type semiconductor.. How are semiconductors made? Certain elements, such as Germanium or Silicon, are not naturally semiconductors but can be made into semiconductors by melting them and adding very small amounts of other chemicals. This process is called doping . Whether a p -type semiconductor or an n -type semiconductor is produced depends on the type of doping chemical used. ( Full Answer )
Conductors allow electricity to pass through them easily and insulators don't let electricity pass through easily. Some examples of conductors are most metals and some examples of insulators are wood, rubber, and plastic.
Materials are classified as being conductors, semiconductors, or insulators according to their resistivity . Resistivity is defined as being ' the resistance of a unit length of a substance of uniform cross section' . In the SI system this equates to the resistance across opposite faces of a one-…metre cube of that substance , and is expressed in ohm metres. Note that a one-'metre cube' is not the same thing as a 'cubic metre'. So, for conductors : resistivity range 10 -8 - 10 -6 ohm metres semiconductors : resistivity range 10 -6 - 10 7 ohm metres insulators: resistivity range 10 7 - 10 23 ohm metres To appreciate the difference between these astronomical figures, consider the following: A 25-mm length of mica (an insulator) of cross-sectional area 2.5 mm 2 cross-sectional area will have a resistance of 100 x 10 15 ohms. A copper wire, having the same cross-sectional area and resistance, will have a length of 14.29 x 10 18 metres! That works out to: 14 290 000 000 000 000 kilometres long !!!! ( Full Answer )

An insulator is a material that is used for its high resistance to electrical current flow. It is used to prevent current from flowing outside of the intended conductor (ie. Ceramic insulators supporting high-voltage power lines). . A semi-conductor on the other hand, has a special property of not …always conducting, and not always not-conducting. The simplest semiconductor is the PN junction diode. Here, the diode conducts and current flows in one direction, but not the opposite polarity. Just like a checkvalve for water or air. . See links.

A conductor will conduct electricity Copper, aluminium, gold, iron and silver are all conductors. An insulator does not conduct electricity. Most plastics and ceramics are good insulators.
A conductor's electrons will transfer easily, allowing it to carry an electrical current and will, literally, conduct the current. An insulator does not exchange electrons easily, so electricity will not flow through it without much resistance, hence insulating the current.
semiconductor fuse is used to save the diodes ,thyristers and IGBTS because the below time is very fast in the case of any short circuit and over current, HRC fuse is mostly used in the power factors panels and its below time is less then semiconducter fuses.

The fundamental difference between inorganic and organicsemiconductors is in the charge transport mechanism. In the former case electrons moving in widebands as delocalized plane waves are subjected to very limitedscattering, and hence, feature relatively high mobility (e.g. ~1.5x103 cm 2 V -1 s -1 … in Si at roomtemperature). In the case of organic semiconductors, the chargetransport is based on carriers hopping between localized statesassociated with organic molecules. In the process electrons undergosignificant scattering which results in very low electron mobilityin organic semiconductors (~1-3cm 2 V -1 s -1 ). ( Full Answer )
