why woods do not radiate electricity?
Radiate?
Woods are insulators, and do not conduct electricity, so if you place an electrical charge on some wood, it does not move.
I frankly am uncertain what you mean by radiate electricity.
Trees can, however, reflect radio and TV waves, and are a major cause of annoying "ghost reflections" and bad TV reception in heavily forested rural areas.
Woods, being natural insulators, do not typically conduct electricity. This is because the structure of wood consists of tightly packed fibers that do not allow free movement of electrical charges. These fibers are made up of materials like cellulose, lignin, and hemicellulose, which have high resistivity to the flow of electric current.
To understand why woods do not radiate electricity, it's important to know how materials conduct electricity. The conduction of electricity depends on the movement of charged particles, either electrons or ions, within a material. In conductors like metals, there are free electrons that can easily move and carry electricity. In insulators like wood, however, there are no such free electrons to facilitate the flow of electrical charge.
To explore this further, we can consider the atomic structure of wood. Atoms in wood are bonded tightly together, resulting in a solid and stable structure. In this arrangement, valence electrons (the outermost electrons of an atom) are firmly localized and do not have the freedom to move around. Consequently, electricity cannot flow freely through wood.
If you were to expose wood to an electrical current, the tightly bound electrons in its structure would resist the flow of electricity. This resistance, measured in ohms, inhibits the electrons from traveling through wood and causes the material to act as an insulator.
In summary, woods do not radiate electricity due to their unique atomic structure, which lacks the free electrons necessary for conducting electrical energy.
