In a superconductor the value of critical density depends upon______________?
Correct answer: D. both (A) and (B)
- A. magnetic field strength
- B. temperature
- C. either (A) or (B)
- D. both (A) and (B)
Explanation
The critical current density of a superconductor varies with both temperature and applied magnetic-field strength, generally decreasing as either becomes more severe. Hence both factors affect it.
