Question 92Electricity & Electronics - QMED
70% to passThe resistance of most conducting materials will change as a result of temperature change. What will happen to the resistance of copper wire when the temperature increases?
Aremains constant
Bincreases in a predictable way
Cchanges in an unpredictable way
Ddecreases in a predictable way
AI Explanation
The correct answer is B) increases in a predictable way. The resistance of most conducting materials, including copper wire, increases in a predictable way as the temperature increases. This is due to the increased thermal agitation of the electrons within the conductor, which leads to more collisions and scattering events, resulting in higher resistance. The other options are incorrect: A) the resistance does not remain constant, C) the change in resistance is predictable, not unpredictable, and D) the resistance increases, it does not decrease.
