How are conductors and insulators different give an example of a conductor and an insulator?

conductors, such as metals, have free electrons, meaning their electrons are not strongly bonded to the atoms and a charge can move easily throughout the whole object, an insulator such as wood does not have free electrons so a charge is likely to stick in one area of the insulator.

Why do you use semiconductor why not conductors and insulators by changing their properties?
We use semiconductors instead of conductors and insulators by changing their properties because the properties of a semiconductor lies between that of a good insulator ant that of a good conductor. Any of the materials obtained depends on the level of doping.
What is the difference between conduct and insulate?
Insulation is keeping the heat inside, trapping it and not letting out. Conduction is letting a flow, such as electricity, pass through the material. for example, metal is a wonderful conductor of heat and electricity, but a bad insulator. However, wool is a good insulator and a bad conductor. :) hope that helps!
Why pin insulator is not used above 33 KV line?
A pin insulator is a ceramic insulator that fitted above the cross-arm of a pole, and which supports the conductor which is secured to the top of the insulator. A suspension insulator is a toughened-glass insulator 'dish' which hangs below a cross-arm of a tower, from which a conductor/s is suspended. For increased insulation levels, dishes may be coupled together to form 'strings'. The manufacturing technique for pin insulators is more expensive than for suspension insulators,and the cost escalates signifcantly with increased voltages, which limits their operating voltage to around 50 kV. In practise, this means limiting their application to 66-kV lines in the United Kingdom (although 33 kV is much more common). Manufacturing costs are approximately proportional to the square (or more!) of the operating voltage. The advantages of using suspension insulators, on the other hand are: less expensive than pin insulators at working voltages above 50 kVeach insulator is designed for a relatively-low voltage, and the required insulation-level is obtained by connecting a suitable number together, to form stringsmechanical stresses are reduced, because suspension insulators allow conductors to swing (whereas pin insulators are rigid)any failure only requires one insulator to be replaced, rather than the entire chainany voltage upgrade can be achieved economically, by adding additional insulatorsRead more: Why_pin_insulator_is_not_used_above_33_KV_line
What do you call the material that covers a conductor?
Most wire conductors are covered with an insulator. This material is intended to prevent accidental connection between multiple conductors or between conductors and other objects that may conduct electrical or electronic signals (including humans).
Is wood a conductor or an insulator of electricity?
Wood is an insulator.
Is a phone a insulator or conductor?
some parts are insulators, some parts are conductors
Is a battery an insulator or conductor?
A battery is a combination of conductors and insulators.
Is a papeclip a conductor or insulator?
If something is a conductor or an insulator depends on the material, not its function. A metal paperclip will be a conductor, since metals are conductors. A plastic paperclip will be an insulator, since plastics generally are insulators.
Is a tire a insulator or a conductor?
Regular car tires are insulators. Some aircraft tires are conductors.
Examples of insulators and conductors?
Insulators: wood, plastic Conductors: Copper, Gold
Why is an insulator never a good conductor?
Because insulators are the opposite of conductors and therefore electricity and heat do not pass through good insulators.
Is glue an insulator or a conductor?
Most glues would be insulators. A few specially formulated 'glues' are conductors.
Are marshmallows insulators or conductors?
Yes, most certified electricians use candy bars to insulate high voltage power lines. If you look at the wires on high grade medical equipment you will notice they are always insulated with the finest candy bars.
Are scissors conductors or insulators?
Depends on what they're made of, not what they are.Anything made of a conducting material is a conductor, whatever it is.Anything made of an insulating material is an insulator, whatever it is.Material properties - conducting or insulating - is more important than shape.Scissors are generally - but not always - made of metal.And metals are usually conductors, making the scissors conductors.But a scissor might have plastic handles. Plastic is usually an insulator, which would make the handles insulators.
What are the examples of insulator and conductor?
The difference between a conductor and an insulator is that a conductor allows electrons to travel. This is because the "outer electrons" of a conductor are not anchored like those of an insulator. Conductors tend to be metals. Some examples of insulators are plastic, glass, rubber and wood.
Use the electron theory to explain how insulators and conductors work?
the same way an insulator and a conductor will work with out the electron theory!
Not a good electrical conductor or insulator?
babies, rocks, cabbage, and habberdasheries are neither good electrical conductors, nor insulators.
