Rubber, wood are the insulators of electricity.Insulators
  • The substances that do not permit the current to move through itself is called as an insulator.
  • The atoms of the insulator have tightly bound electrons which cannot  move readily.
  • If we transfer some amount of charge to such an element at any point, the charge remains at the same point and does not get spread across the surface.
  • Plastic, pure water, wood and rubber were insulators.

Answer:

The names of some insulators of electricity are styrofoam, wax, plastic, dry air, rubber, ceramics, teflon, glass, asphalt, quartz, porcelain and mica.

Explanation:

Insulating materials do not allow electric current or charge to move freely. Insulating materials give electrons very little freedom to drift from atom to atom. Thus, insulators are poor conductors of electricity. In general, insulators are very useful in homes, offices, streets, etc. They are used in electrical appliances and equipment. Unfortunately, human skin is one of the best conductors of electricity. In addition, the presence of insulating materials prevents and protects electrical equipment from generating high voltages.

Some examples of insulators are as follows: styrofoam, wax, plastic, dry air, rubber, ceramics, teflon, glass, asphalt, quartz, porcelain and mica.
