When insulators are rubbed, charges are transferred through a process called triboelectric charging. Insulators have high electron affinities, making it easier for them to gain or lose electrons during rubbing. Conduction, on the other hand, requires mobile electrons which are more restricted in insulators compared to conductors.

Is carbon a insulator or conductor?

Carbon being a tetra valent forms covalent bonds. So basically carbon is not a good conductor. But at the same time it is not an insulator. When electric potential difference is maintained then bonds could be easily broken and movement of charges becomes easier. So it becomes a conductor but a good conductor. Hence carbon is used to make resistors.


Does a charge move easier through metal or air?

A charge moves easier through metal because metals are good conductors of electricity, allowing the charge to flow more freely. Air is a poor conductor of electricity, so charges do not move as easily through it.


Why is it easy to create a current in a conductor and not in an insulator?

It is easier to create a current in a conductor because conductors have free-flowing electrons that can move easily when a voltage is applied, allowing for the flow of current. Insulators, on the other hand, have tightly bound electrons that do not move freely, making it more difficult to establish a current flow in them.


Will objects float better in rubbing alcohol or water?

Objects will float better in rubbing alcohol than in water because rubbing alcohol has a lower density than water. This means that objects will displace less liquid in rubbing alcohol, making it easier for them to float.


Why does salt water is good conductor of electricity?

Salt water is a good conductor of electricity because it contains ions - charged particles - from the dissolved salt. These ions allow electric current to flow through the water by carrying the charge. The presence of ions in the solution makes it easier for electricity to transfer from one electrode to another.

Why is it easy to charge a non conductor although it is with the hands?

It is easier to charge no-conductors with the hands because the charge generated will not be discharged through our bodies.


Why is it easier to charge polythene by rubbing but not copper?

Polythene has a higher tendency to gain electrons from other materials due to its structure, making it easier to become negatively charged when rubbed. Copper, on the other hand, has a more stable electron configuration and lower affinity for gaining or losing electrons, making it harder to charge through rubbing.

How are porous materials used as thermal insulators?

actually the insulator is the dead air in the pores a better insulator is vacuum (only radiation) air has conduction convection and radiation air is easier to handle near sea level


When a conductor is charged the charge moves to the outer surface of the conductor?

True. For instance in a wire, all of the charge is carried on the outside surface of the wire, and not down the center. Why?? Because when the electricity flows down the wire it causes alternating magnetic fields which cause alternating eddy currents within the wire. An eddy current is bascially an electromagnetic area of turbulence, and in this instance makes the flow of electrons easier on the outer edge of the wire. The higher the frequency that the electricity flows through the wire, the stronger the eddy currents and a thinner section of wire will carry the charge.


Is water a better conductor than metal?

No, water is not a better conductor than metal. Metal is a much better conductor of electricity than water because of its free-flowing electrons that allow for easier passage of electric current. Water, on the other hand, is a poor conductor of electricity due to its lack of free electrons.


Why would a window pane have 2panes of glass with air between them?

Trapped air is a good insulator, making it easier to keep the climate inside under control.
