Question

should the heating element of an electric iron be made of iron silver or nicrome wire? why

Answer 1

should be made of nichrome wire because resistivity of nichrome is high.Its high resistivity causes nichrome to heat up faster, when an electrical current is passed electricity moves through the wires, giving heat to the element.

hope it helped

Answer 2

Nichrome

Because of following reasons :-

1. Nichrome is an Alloy which has higher resistivity than pure metal.

2. It has high melting point and does not burn readily or oxidise
