Question

give to reasons of nichrome alloy is used for making the heating element of an electric iron.
(write point wise)​

Answer 1

Answer:

Nichrome is used for making heating element of electrical appliances. Because nichrome does not oxidize and burn easily at high temperature i.e.it has higher melting and boiling point than metals. Thus it does not melt even when a large amount of heat is produced due to passage of current.

Answer 2

Answer:

Nichrome alloy is used for making the heating elements of electrical appliances because:

(i) nichrome has very high resistivity.

(ii) nichrome does not undergo oxidation (or burn) easily even at high temperature.
