Korkearesistiveille

Korkearesistiveille refers to materials that exhibit high electrical resistance. This property means that these substances significantly impede the flow of electric current when a voltage is applied across them. In simpler terms, they are poor conductors of electricity.

The opposite of high resistance is low resistance, which is characteristic of good conductors like metals. Materials with high resistance are often referred to as insulators or dielectrics. These materials are crucial in electrical engineering and everyday life for their ability to prevent or control the passage of electricity.

Examples of high-resistance materials include rubber, glass, ceramics, and most plastics. These are commonly used in applications where electrical insulation is necessary to prevent short circuits, protect users from electric shock, and ensure the proper functioning of electrical devices. For instance, the plastic coating on electrical wires is a high-resistance material that prevents current from escaping the conductor. Similarly, ceramic insulators are used on power lines to keep the high-voltage wires from touching the supporting structures.

The specific value of resistance is measured in ohms (Ω). A material with a high resistivity (a measure of how strongly a material opposes electric current) will have a high resistance for a given size and shape. The concept of high resistance is fundamental to understanding how electrical circuits work and how to safely manage electrical energy.
