What happens to the resistance of a conductor when its temperature increases? The most useful approach is to identify the physical quantity, phenomenon, law, or device named in the stem and connect it with its standard definition. Here, the relevant answer is “Increases.” A sound solution relies on the governing concept rather than a memorised option letter, because option order may change in another paper. The distractors in this question—Decreases, Remains the same, Becomes zero—do not satisfy the exact condition stated. The final selection must agree with the explanation and marked answer: Increases. If the topic involves an equation, identify every symbol and its unit.
