Quick Answer: Should the heating element of an electric iron?

Nichrome wire should be used as the heating element in an electric iron. … Should be made of nichrome wire because resistivity of nichrome is high. Its high resistivity causes nichrome to heat up faster, when an electrical current is passed electricity moves through the wires, giving heat to the element.

Should the heating element of an electric iron be made of iron Silver or nichrome?

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.

Should the heating element of an electric iron Class 10?

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.

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

Nichrome is an ideal material for heating elements for an electric iron also because the oxide layer formed helps to protect the inner material from oxidizing which doesn’t let internal wires burn. The alloys offer high strength, excellent fabricability, and outstanding corrosion resistance.

What happens when the heating element made of nichrome is 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. Secondly its melting point is also low as compared with nichrome.

Where are the elements found in the clothes iron?

Parts of electric Iron [contd…] The heating element is present between the sole plate and pressure plate. It is pressed hard between the two plates. The heating element consists of nichrome wire wound around a sheet of mica.

What are the effects of an electric current?

What is the function of fuse in an electric appliance?

The fuse breaks the circuit if a fault in an appliance causes too much current to flow. This protects the wiring and the appliance if something goes wrong. The fuse contains a piece of wire that melts easily.

Which part of an electric iron becomes hot and gives out heat?

When electric current is passed through an electric heating appliance by connecting it to a power socket through insulated copper wires (called cord’ or ‘connecting cable’), then a large amount of heat is produced in the heating element (or coil) due to which the heating element become red-hot.

What is the element in respect of heating effect?

A typical heating element is used a coil , ribbon ( straight or corrugated ) , aur strip of wire that gives of heat much like a lamp filaments . When an electric current through it , it glows red hot and converts the electrical energy passing through it into heat , which it readiates out in all directions .

Which element is present in iron box?

Nichrome is used as a heating element in an electric iron . It is an 80 percent nickel and 20 percent chromium alloy with nickel and chromium. It has a high melting point of 1400 degrees C.

Which of the following does not work on the heating effect of current?

Answer: fan doesn’t use the heating effect of current…..

What does nichrome wire do?

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.
