Question

assertion- alloys are used to make heating elements of electronic iron. heater etc.
reason- resistivity of alloy Is higher than its constituent metal but its melting point is lower than the constituent metal
i have written option (b) is this correct

because alloys have higher resistivity and doesn't oxidise which isn't mention in thre. reason ​

Answer 1

both r correct and reason explain assertion

Answer 2

Answer: option (a)

Explanation: what do we need to do with melting point in heating effect. But if we look on the other side Alloys are used in fuse if we look at Joules heating law so for me its clear they have low melting points.

Anyways.. look for other answers too..
