Question

Should the heating element of an electric iron be made of iron, silver, or nichrome?

Answer 1

• In electrical heating devices, the heating effect of electricity is utilized. In these devices, we should use alloy which provides a more heating effect when a current passes through it.
• The alloy has more resistance than that of metals.
• Nichrome is an alloy while iron and silver are metals.
• More is the resistance of material more is its heating effect.

Final answer:

Hence, nichrome with more resistance is used as the heating element in an electric iron.
