What property of a good insulator prevents the flow of heat or electricity?

• A. Conductivity
• B. Resistance
• C. Absorption
• D. Conduction

Answer: (B)

The property of a good insulator that prevents the flow of heat or electricity is resistance. Insulators are materials designed to limit the movement of charged particles, thereby impeding the transfer of electrical current. High resistance means that the material does not allow electrons to flow easily, effectively minimizing electrical conduction. This property is crucial in various applications, such as electrical wiring and thermal insulation, where the goal is to keep heat and electrical energy contained within a specific area, preventing loss and enhancing safety. Conductivity, absorption, and conduction refer to the ease with which materials allow heat or electrical currents to pass through them. Conductivity specifically measures how well a material can conduct electricity or heat; a good insulator has low conductivity. Absorption relates more to a material's ability to take in energy, while conduction pertains to the direct transfer of heat through a substance. None of these properties effectively describe the insulating capability that is fundamentally based on resistance.
