Question

Which one of the following heater element used in electric press-
A. Copper wire
B. Nichrome wire
C. Lead wire
D. Iron wire

Answer 1

Hint: To answer this question we should have basic information about electric Press and about all the options like copper wire, nichrome wire, lead wire, iron wire then we only be able to answer this type of questions.

Complete step-by-step answer:
Electric press: We generally use this equipment in our house. It runs through electricity that means when we pass current through it the material used becomes hot so its flat surface becomes hot and we use that flat surface to flatten our clothes.

Copper wire: As we know copper is a good conductor of electricity and it is easily available in nature so we use it as power transmission and to transfer current from source to household. Best conductor is silver but silver is costly too but copper is not much costly so we use copper wire in replacement of silver wire.

Nichrome wire: We should have knowledge that nichrome wire is an alloy of chromium and nickel. And also we should have known that its melting point and boiling point are too high so we can use it as a heating element and that is the reason it is always used in appliances like electric press and heater as heating element.

Hence, Nichrome is Used in an Electric Iron as a heating Element . Its price also favours its use that means it is not much costly.

Hence option B is the correct option.

Note: Whenever we get this type of question the key concept of solving is we have to understand the use of every wire and also knowledge about principles of iron on which it works.
