To solve the problem, we will analyze the situation step by step. ### Step 1: Understand the Setup We have a steel wire that is initially heated to red-hot temperatures. When a current flows through the wire, it generates heat due to its resistance. Half of this wire is then immersed in cold water. **Hint:** Consider the initial conditions of the wire and how the immersion in cold water affects its temperature. ### Step 2: Analyze the Effect of Cold Water ...

Assertion : Current is passed through a metallic wire, heating it red. Half of its portion is cooled by cold water jacket, then rest of the half portion become more hot. Reason: Resistances decreases due to decrease in temperature and so current through wire increases.

Assertion: Current is passed through a metallic wire, heating it red. When cold water is poured on half of its portion, then rest of the half portion become more hot. Reason: Resistance decreases due to decrease in tem perature and so current through wire increases.
