Which of the following materials is preferably used in making heating elements of electrical heating devices?
ATin-lead alloy
BNichrome
CTungsten
DConstantan
Answer:
B. Nichrome
Read Explanation:
Nichrome is an alloy commonly used in heating elements due to its high resistance and ability to withstand high temperatures.
Nichrome is used as a heating element due to its high resistivity, ability to withstand high temperatures, resistance to oxidation, thermal stability, and ease of fabrication.
These properties make it an ideal choice for applications where heat generation is necessary.
