Why are you use nichrome wire in electric iron or electric heater?

Nichrome wire should be used as the heating element in an electric iron. The reasons are mentioned below: High resistivity thus ensuring the wires to heat up faster. High specific heat which provide enough heat to the element.

Why is nichrome alloy used for heating appliances?

Hint: Nichrome is an alloy that conducts electricity although it has high resistivity, due to this property it is used for making heating elements of electrical appliances. It has a high specific resistivity due to which it opposes the flow of current and hence it has a high resistance too.

What is nichrome wire used for?

Nichrome wire is an alloy made from nickel and chromium. It resists heat and oxidation and serves as a heating element in products such as toasters and hair dryers. Hobbyists use nichrome wire in ceramic sculpture and glassmaking. The wire can also be found in laboratories, construction and specialized electronics.

Why is the element of electric iron made up of nichrome?

Whenever current passes through Nichrome heat produced by it is very high in comparison to aluminium, copper, and constantan due to high resistivity. Hence the heating element of an electric iron is composed of nichrome.

Should the heating element of an electric iron be made of iron silver or Nichrome wire justify giving reasons?

The heating element of an electric iron should be made of nichrome wire because: \((i)\) Resistivity of nichrome is greater than that of iron and silver, so more heat is produced in the nichrome wire due to the flow of current. \((ii)\) Nichrome wire does not oxides (or burn) easily even at higher temperature.

Why is nichrome used for heating elements of heaters and toasters?

The heating element in a toaster is made of nichrome wire. Nichrome has low resistivity. It has a very high melting point (1150°C), so that nichrome is used to make high-temperature wires.

Why an alloy like nichrome is used as a filament in electric heaters Geysers electric iron and electric toasters give two reasons?

Nichrome doesn’t burn easily at high temperatures as it has higher melting and boiling point than metals.

Can nichrome wire conduct electricity?

In metal, a wire of nichrome (alloy of mainly nickel and chrome) is a hard material to conduct electricity (electrical resistance is high). For this reason, a nichrome wire is used for electric stoves and toasters.

What is used to electric iron in heating?

Nichrome is an alloy of nickel and chromium that is used as the heating element in most electric irons.

Which heating element is used in electric iron and heater and why?

So, from all the given Nichrome is used as a heating element in electric iron which is an alloy consisting 80\% of Nickel and 20\% of Chromium melting point of this element is 1400 degree Celsius with high resistance which makes this element best for using as a heating element.

What happens when the heating element made of nichrome in an electric iron is replaced by copper?

If the heating elements of electric iron made of nichrome will be replaced by copper then the current will not be converted into heat because it will offer very low resistance and hence, will not glow.
