Properly of low temperature co-eflficient of heating element is desired due to which of the following reasons ?
Correct answer: C. Both (A) and (B)
- A. To avoid initial rush of current
- B. To avoid change in kW rating with temperature
- C. Both (A) and (B)
- D. Either (A) or (B)
Explanation
A low temperature coefficient keeps the element resistance nearly constant as it heats, reducing the cold-start current surge and preventing substantial change in its kW rating. Thus both listed reasons are valid.
