Sähköneristysominaisuus

Sähköneristysominaisuus refers to the ability of a material to resist the flow of electric current. This property is crucial for electrical safety and the proper functioning of electronic devices. Materials with high electrical resistance are considered good insulators, while those with low resistance are conductors. The inverse of electrical resistance is electrical conductivity, which measures how easily electric current can flow through a material. The effectiveness of an insulating material is often quantified by its dielectric strength, which is the maximum electric field strength it can withstand before it breaks down and begins to conduct electricity. Factors such as temperature, humidity, and the presence of impurities can significantly affect a material's electrical insulating properties. Common insulating materials include rubber, plastic, glass, and ceramics. These materials are used to coat electrical wires, construct electrical components, and separate conductive parts in various electrical and electronic applications to prevent short circuits and electric shock.
