1. Its melting point is high
2. Its resistivity is large
3. It is tensile
4. It does not oxidize easily by the oxygen of the air when heated
Choose the correct answer from the options given below:
- A (A), (B) and (D) only
- B (A), (B) and (C) only
- C (A), (B), (C) and (D)
- D (B), (C) and (D) only
Answer & Solution
Correct Answer
(A) (A), (B) and (D) only
Step-by-step Solution
Detailed explanation
High Melting Point (A): It can withstand extreme temperatures without melting. High Resistivity (B): Its high resistance allows it to efficiently convert electrical energy into heat energy ( \(H=I^2 R t\) ). Resistance to Oxidation (D): It does not react easily with oxygen at…
