Question

Why are the electrical heating devices made up of an alloy rather than the pure metal?

Answer 1

Answer:

because alloy is the good conductor of heat and electricity

Answer 2

Answer:

Explanation:

RESISTANCE which is an important factor for production of heat . if resistance across a wire increases the heat generated will also be incresaes.

it is also dependent on area of cross section and many other factors
