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.
What else can I help you with?
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.
Can a substance be both a conductor and a insulator?
No, a substance cannot be both a conductor and an insulator simultaneously. Conductors allow the flow of electricity, whereas insulators do not. Materials are classified as conductors or insulators based on their ability to conduct electricity.
Is a battery an insulator or conductor?
A battery is a combination of conductors and insulators.
What is the oppersit of insulator?
The opposite of insulator is conductor.
Examples of insulators and conductors?
Insulators: wood, plastic Conductors: Copper, Gold
Is a tire a insulator or a conductor?
Regular car tires are insulators. Some aircraft tires are conductors.
In physics what's the opposite of insulator?
The opposite of an insulator in physics is a conductor. Conductors allow electrical current to flow easily, while insulators inhibit the flow of current.
Can something be an insulator and a conductor?
No, a material cannot be both an insulator and a conductor at the same time. Insulators have high resistance to electrical flow, while conductors have low resistance.
What is a hypothesis for conductors and insulators?
A hypothesis for conductors and insulators could be: "If a material allows the flow of electrical current easily, then it is a conductor. If a material inhibits the flow of electrical current, then it is an insulator."
Is glue an insulator or a conductor?
Most glues would be insulators. A few specially formulated 'glues' are conductors.
What material has resistance between a conductor and a insulator?
Semiconductors have resistance levels between that of conductors and insulators. They conduct electricity better than insulators but not as well as conductors, making them useful in electronic devices. Examples include silicon and germanium.
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.
