Question

should the heating element of an electric iron be made of iron , silver or nichrome wire? jusyify giving the reasons .​

Answer 1

Explanation:

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

Answer 2

Answer:

It can only be made up of an alloy like nichrome

Explanation:

because only alloys have high melting point or high resistance as if u use silver or iron it will make current to flow but we want heat to iron our clothes so as u know resistance is directly proportional to heat or temperature so if u increase resistance by using nichrome wire it will produce heat due to high resistance that will make ur got ironed by electric iron
