Why are alloys commonly used in electrical heating devices?
(N/A) Alloys are commonly used in electrical heating devices because of the following reasons:
$1$. They have high resistivity,which allows them to produce more heat when an electric current passes through them.
$2$. They do not oxidize (burn) readily even at high temperatures,which increases the durability and lifespan of the heating element.
