Question

in the electrie equipments producing heat
eg.iron, electric heater ,boilers, toaster, etc an
alloy such as Nichrome is used not pure metal​

Answer 1

Answer:

Because alloys like nichrome have a higher resistivity than pure metals, they will easily heat up when a tiny amount of current is sent through them.

Explanation:

• As a result, an alloy such as Nichrome, rather than pure metals, is used in electric equipment that produces heat, such as iron, electric heaters, boilers, toaster, and so on.
• Nichrome has a higher resistivity than pure metal.
• Nichrome has a higher melting point than pure metal.
• When heated in air, nichrome does not oxidise, whereas metal does.
