Question 3(ii)
How does increase in the temperature affect the specific resistance of a metal and semiconductor?
Specific resistance increases with increase in temperature for metals but it decreases with the increase in temperature for semiconductors.
Key Concepts Covered
This question tests your understanding of the following concepts from the chapter Solved Sample Paper 5: Question, Increase, Temperature, Affect, Specific, Resistance. These are fundamental topics in Physics that students are expected to master as part of the ICSE Class 10 curriculum.
A thorough understanding of these concepts will help you answer similar questions confidently in your ICSE examinations. These topics are frequently tested in both objective and subjective sections of Physics papers. We recommend revising the relevant section of your textbook alongside practising these solved examples to build a strong foundation.
How to Approach This Question
Read the question carefully and identify what is being asked. Break down complex questions into smaller parts. Use the terminology and concepts discussed in this chapter. Structure your answer logically — begin with a definition or key statement, then provide supporting details. Review your answer to ensure it addresses all parts of the question completely.
Key Points to Remember
- State the relevant law or principle before applying it.
- Include units in every step of your calculation.
- Draw diagrams where applicable (ray diagrams, circuit diagrams, free-body diagrams).
- Connect theoretical concepts to real-world applications.
