An alloy used in making heating elements for electric heating devices is?
Answer: C
Nichrome - an alloy of about 80 per cent nickel and 20 per cent chromium - is used for the heating elements of electric heaters, irons and toasters.
It has high resistivity, so it heats strongly for a modest current, and it does not oxidise away at red heat because the chromium forms a protective oxide skin.
