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).
