On the contrary, insulators have higher resistance than conductors. Resistance refers to resisting a flow of electricity, making it more difficult for electricity to flow. Conductors conduct electricity, they make it easy for electricity to flow. Insulators prevent the flow of electricity.
What else can I help you with?
What shows how conductors insulators superconductors and semiconductors rank in order of least resistance to most resistance?
Superconductors have no resistance, making them the best conductors. Semiconductors have moderate resistance. Conductors have low resistance, making them better conductors than insulators, which have high resistance, making them the poorest 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.
Which has the lowest resistance semiconductors superconductors insulator conductor?
Superconductors have the lowest resistance of all materials, with resistance dropping to zero when they are cooled below a certain critical temperature. Conductors have lower resistance than semiconductors and insulators, which have significantly higher resistance and do not conduct electricity as effectively.
Why do conductors have a lower specific heat than insulators?
Conductors have lower specific heat compared to insulators because conductors have more free electrons that are available to transfer heat energy quickly through the material. Insulators have fewer free electrons and therefore heat is transferred more slowly through the material, resulting in a higher specific heat capacity.
Can insulators offer resistance to the flow of electric current?
Yes, different grades of insulators can offer different levels of resistance to current flow of electrons within a closed circuit. For instance the flow of current would be different between wood and rubber, both insulators.

Does Semiconductor materials are substances with properties between those of a conductor and an insulator?
Yes, that is correct. Semiconductor materials have properties that fall between those of conductors and insulators. They have electrical conductivity higher than insulators but lower than conductors, making them essential for designing electronic devices such as transistors and diodes.
Do semi conductors permit flow of electricity better than insulators?
Yes, semiconductors allow the flow of electricity better than insulators, but not as well as conductors. Semiconductors have conductivity values between those of conductors and insulators, making them useful for controlling the flow of electric current in electronic devices.
Do conductors have more electrons than an insulator?
No, conductors do not have more electrons than insulators. In fact, conductors have loosely held electrons that are free to move, allowing the flow of electric current, while insulators have tightly bound electrons that do not flow easily.
What is an object that conducts electricity better than insulators but not as well as conductors?
Semiconductors are materials that conduct electricity better than insulators but not as well as conductors. They have properties that allow them to be used in electronic devices to control the flow of electrical currents.
Are substances like wood and plastic better heats conductors like metal?
No, substances like wood and plastic are not as good heat conductors as metals. Metals have free electrons that allow heat to transfer quickly through them, while wood and plastic are insulators with a higher resistance to heat flow.
What does it mean when nonmetals are better insulators than conductors?
Nonmetals have higher electrical resistance compared to metals, making them better insulators. This means that they are less likely to allow the flow of electricity through them. Nonmetals have fewer free electrons that can carry electrical charge, which hinders their ability to conduct electricity.
How do electrons in conductors move about freely than the electrons in insulators what?
Electrons in conductors, such as metals, are loosely bound to their atoms and can move freely through the material, facilitating the flow of electric current. In contrast, electrons in insulators are tightly bound to their atoms and do not have the ability to move freely, which prevents the flow of electric current. This difference in electron mobility is due to the varying atomic structures and energy band gaps in conductors and insulators. As a result, conductors allow for efficient electron transport, while insulators resist it.
