Assertion (A): Alloys are commonly used in electrical heating devices like electric iron and heater.

Reason (R): Resistivity of an alloy is generally higher than that of its constituent metals but the alloys have low melting points then their constituent metals.

 

Answer:

The resistivity and melting point of alloys are much higher than their constituent metals . Thus, they are commonly used in electrical heating devices like electric iron or heaters.

Thus,

  • Assertion is true.
  • Reasoning is false.

So, the correct answer is (c).
