What type of resistance do insulators exhibit?

• A. Low resistance
• B. Medium resistance
• C. High resistance
• D. No resistance

Answer: (C)

Insulators exhibit high resistance, which means they do not allow the flow of electric current easily. This property is essential in various applications, particularly in electrical and electronic systems, where control over the flow of electricity is crucial. High resistance in insulating materials prevents unwanted currents from flowing, ensuring safety and proper functioning of devices. Materials like rubber, glass, and certain plastics are common insulators due to their ability to resist the flow of electrons. Their high resistance is a key characteristic that helps protect wires and components from electrical leakage, reducing the risk of short circuits and other electrical hazards. In contrast, materials with low resistance, such as metals, allow for easy flow of electrons, which is not desirable when insulating is necessary. By understanding the high resistance feature of insulators, one can appreciate their vital role in the safety and effectiveness of electronic and electrical systems.
