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

The nichrome is a material made of 80% nickel and 20% . Nichrome is a material that delivers high mechanical strength and also it offers high creep strength. It has a high melting point such that it can sustain high temperatures.

Why nichrome is used in electric iron?

Nichrome is made up of 80% nickel and 20% chromium. Nichrome is a material with high mechanical strength as well as high creep strength. It has a high melting point, allowing it to withstand extreme temperatures. … These characteristics make nichrome an ideal alloy for use in electric iron heating elements.

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 the heating element of an electric iron made of nichrome explain it in the term resistivity of the material?

Because nichrome is an alloy which has high melting and boiling points also it’s resistivity is high so it doesn’t melt easily even when it is red hot. When electricity is passed through nichrome wire so it produces a lot of heat which is required for such heating elements such as electric iron etc.

Why do we use nichrome in an electric heater Class 7?

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

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

Nichrome, a non-magnetic 80/20 alloy of nickel and chromium, is the most common resistance wire for heating purposes because it has a high resistivity and resistance to oxidation at high temperatures.

What is the element of an electric iron made of?

The nichrome is a material made of 80% nickel and 20%. Nichrome is a material that provides high mechanical strength and also it provides high creep strength.

Should the heating element of an electric iron be made up of iron Silver or Nichrome wire?

The correct answer is Nichrome. The heating element in an electric iron is an alloy consisting of 80% of Nickel and 20% of Chromium. The melting point of Nichrome is 1400º C with high resistance which makes this element best for use as a heating element.

Should the heating element of an electric iron be made of iron Silver or Nichrome wire justify giving three 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 wire generally used as heating element in heating appliances give any three reasons?

In most of the household heating appliances, nichrome element is used because of the following reasons: (i) Its melting point is high. (ii) Its resistivity is large. (iii) It can be easily drawn into thin wires (i.e., it’s ductile).

Why does Nichrome wire heat up?

Nichrome due to its high resistivity does not allow the electric energy easily to pass through it. This electrical energy is changed into heat energy. So nichrome wire gets heated in an electric circuit.
