Insulators are by nature poor electrical conductors. The charge left behind by friction that involves two surfaces (e..g. rubbing your dry thick socks on the carpet during walking on a cold dry day; or dry hair and a nylon sheet) remains immobile on each surface. One surface will have a positive charge and the other surface, an equal amount of negative charge, so the total charge is still zero. But, these charges are on two separate objects. For each object, the opposite charge does not have an easy time of migrating from the bulk of the object to the surface to neutralize the surface charge. Neutralization can only occur with external help such as leaving the object alone to expose to room moisture for a long time or a quick contact with a conductor (a door knob) or an annoying sibling ;-).
What else can I help you with?
How are insulators charged?
Insulators can be charged by coming into contact with a charged object, inducing a separation of charge within the insulator. This can happen through processes such as friction, conduction, or induction, leading to the insulator having a net positive or negative charge.
Are materials that can be statically charged conductors or insulators?
Materials that can be statically charged can be either conductors or insulators. Conductors allow electricity to flow through them easily, which can lead to static charging under certain conditions. Insulators, on the other hand, do not conduct electricity well and can also become statically charged due to the buildup of excess charge.
Materials that you can charge up by rubbing are they conductors or insulators?
Materials that can be charged up by rubbing (like wool or plastic) are typically insulators. Insulators do not allow electricity to flow easily, so when they build up a charge through static electricity, it stays localized on the object. Conductors, on the other hand, allow electricity to flow freely through them.
Can an insulator be charged?
Yes, insulators can be charged by gaining or losing electrons, leading to a buildup of static electricity on their surface. However, insulators are less conductive than conductors, so the charge typically remains localized on the surface without flowing easily.
Is a marble a good insulators?
Marbles are not good insulators because they are made of dense material and can conduct heat easily. Insulators are materials that do not allow heat to flow through them easily, whereas marbles are more likely to transfer heat.

How do charged conductors and insulators differ from each other?
Insulators prevent electricity or energy from going through them. Conductors allow electricity/energy to easily pass through.
Which material get easily charged by rubbing and what such material is called?

What cannot be charged easily by friction 1 a plastic scale 2 a copper rod 3an inflatted balloon 4a woolen cloth?
A copper rod cannot be charged easily by friction due to its low tendency to gain or lose electrons. Woolen cloth, an inflated balloon, and a plastic scale can be charged more easily through the transfer of electrons.
How do object charged by friction?
how objects become charged by friction
Charges do not flow easily through?
Insulators.
How does friction cause insulators to become charged?
Friction involves two substances rubbing against each other. As this happens, one substance may lose electrons, thus becoming positively charged. Consequently, the other substance gains these electrons, becoming negatively charged.

What kind of materials become electrically charged when they are rubbed together?
