  1. AIt has high resistivity and a high melting pointCorrect answer
  2. BIt has low resistivity and a low melting point
  3. CIt has low resistivity and a high melting point
  4. DIt has high resistivity and a low melting point
Show AnswerHide Answer

Answer

A. It has high resistivity and a high melting point

Show ExplanationHide Explanation

Explanation

A heating-element alloy needs useful resistivity and the ability to withstand high operating temperatures. Nichrome also resists oxidation. No single exact melting temperature is necessary because commercial alloy compositions vary.
