To determine the temperature at which a carbon resistor has a resistance of 995 ohms, starting from 1000 ohms at 20 degrees Celsius, one must consider the relationship between resistance and temperature, typically described by the temperature coefficient of resistance. The discussion highlights a lack of resources, including textbooks, which complicates understanding the necessary equations. Participants suggest using online resources for guidance and emphasize the importance of distinguishing between conductivity and resistivity in calculations. The conversation reflects frustration over the abrupt change in teaching and the need for foundational knowledge in the subject. Overall, understanding the principles of resistivity and temperature dependence is crucial for solving the problem.
