Alloys are commonly used in electrical heating devices, like electric iron etc., because |
|||
|
(a) |
alloys have higher resistivity than that of its constituent metals |
(b) |
alloys do not burn at higher temperatures |
|
(c) |
alloys do not oxidize at higher temperatures |
(d) |
all of the above |
