What are 4 poor conductors?
2 Answers
Four poor conductors of electricity (also known as insulators) are:
1. **Rubber** - Often used in electrical insulation.
2. **Wood** - Especially when dry, it doesn’t conduct electricity well.
3. **Glass** - Excellent insulator, used in various applications to prevent electrical flow.
4. **Plastic** - Commonly used in coatings and casings for electrical devices.
These materials are effective at preventing the flow of electrical current.

Poor conductors, or insulators, are materials that do not allow heat or electricity to pass through them easily. Here are four common examples:
1. **Rubber**: Rubber is widely used as an insulator in electrical wiring and other applications because it resists the flow of electricity. Its molecular structure does not allow free movement of electrons, which is essential for conducting electricity.
2. **Glass**: Glass, especially when it’s not specially treated, is another poor conductor. It is used in various applications where insulation is needed, such as in windows or as an insulating layer in electrical components. The electrons in glass are tightly bound and do not move freely, which makes it an effective insulator.
3. **Wood**: While wood can conduct electricity to some extent if it’s moist, dry wood is a poor conductor. Its structure is made up of cellulose and other organic compounds that do not allow electrons to flow freely. This is why wooden handles are often used for tools to prevent electrical shock.
4. **Plastic**: Many plastics are poor conductors of electricity. They are used extensively in electrical insulation and protective coatings because their molecular structure does not support the flow of electrical currents. The polymers in plastics have tightly bound electrons and lack free-moving charge carriers.
These materials are valuable in various applications where preventing the flow of electricity or heat is crucial, such as in electrical insulation, thermal insulation, and protective coverings.
