Electric Toaster : Small Industries Service Institute Takyelpat Industrial Estate Imphal has designed an Electric toaster which is operated at 220 volts A.C., single phase and available in four different rated capacity such as 600 W, 750 W, 1000 W and 1250 W.
The heating element is made of nichrome 80/20 (80% nickel, 20% chromium), since Nichrome does not get oxidise readily at high temperature and have higher resistivity, so it produces more heat. The element is wound separately on Mica sheets and fitted with body of toaster with the help of ceramic terminals.
Heating element of the toaster is made of:
- a)copper.
- b)nichrome.
- c)chromium.
- d)nickel.
Correct answer is option 'B'. Can you explain this answer?

Heating Element of the Electric Toaster
The heating element of the electric toaster is made of nichrome (option B).
Explanation:
1. Purpose of the Heating Element:
The heating element in an electric toaster is responsible for generating heat that is necessary for toasting the bread slices. It is a crucial component that converts electrical energy into heat energy.
2. Material Selection for the Heating Element:
The material chosen for the heating element is nichrome. Nichrome is an alloy composed of 80% nickel (Ni) and 20% chromium (Cr). The selection of nichrome for the heating element is based on the following characteristics:
- Resistance to Oxidation: Nichrome does not readily oxidize at high temperatures. When the toaster is in use, the heating element becomes extremely hot. The resistance of nichrome to oxidation ensures that it remains durable and does not deteriorate over time due to exposure to high temperatures.
- Higher Resistivity: Nichrome has a higher resistivity compared to other materials like copper. Resistivity is a measure of a material's ability to resist the flow of electric current. The higher resistivity of nichrome allows it to generate more heat when an electric current passes through it. This property is essential for achieving the desired toasting temperature quickly.
- Heat Production: The primary purpose of the heating element is to produce heat. Nichrome, with its high resistivity, effectively produces the desired amount of heat required for toasting bread slices. This ensures that the toast is evenly and efficiently toasted.
3. Construction of the Heating Element:
The heating element is constructed by winding nichrome wire separately on Mica sheets. Mica is an excellent insulator and can withstand high temperatures. The nichrome wire is securely fitted to the body of the toaster using ceramic terminals. This construction ensures that the heat generated by the heating element is efficiently transferred to the bread slices.
To summarize, the heating element of the electric toaster is made of nichrome (80% nickel, 20% chromium) due to its resistance to oxidation, higher resistivity, and ability to produce the necessary amount of heat for toasting.
