The resistance of an insulating material ______ as the temperature inc...
Explanation:
Insulating materials are materials that have high resistivity and are used to prevent the flow of electricity. The resistance of an insulating material is directly related to its temperature.
Effect of Temperature on Resistance:
- As the temperature of an insulating material increases, its resistance decreases.
- This phenomenon is known as "negative temperature coefficient of resistance".
- The atoms in an insulating material vibrate more at higher temperatures, which leads to more collisions with electrons. These collisions make it easier for the electrons to flow, thus reducing the resistance.
Consequences:
- The decrease in resistance with increasing temperature can be a concern in certain applications where stability is crucial.
- It is important to consider the temperature coefficient of resistance when designing circuits that involve insulating materials.
Importance of Understanding Temperature Effects:
- Understanding how temperature affects the resistance of insulating materials is crucial in various fields such as electrical engineering, materials science, and electronics.
- By taking into account the temperature coefficient of resistance, engineers can design more reliable and efficient systems.
In conclusion, the resistance of an insulating material decreases as the temperature increases due to the negative temperature coefficient of resistance. This relationship is important to consider in various applications to ensure the proper functioning of electrical systems.

For insulating materials, the resistivity decreases as the temperature is increased. For metals, however, the resistance increases due to an increase in temperature. This is used as a key characteristic while distinguishing the two.
