Variation of Resistance with Temperature: Practice Problem & Solution

Specific resistance of a conductor increases with: (2002)
Increase in temperature
Increase in cross section area
Increase in cross section and decrease in length
Decrease in cross section area

Solution Explained:

To solve this problem, we apply the core principles of Variation of Resistance with Temperature. Understanding the underlying formula is key to arriving at the correct answer below:

Specific resistance (resistivity) is an intrinsic property of a conductor that depends on temperature and material, increasing as temperature rises.
