Read the following text and answer the following questions on the basis of the same: 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.
Insulating materials used in the device are:
- a)Mica
- b)Ceramic
- c)Mica, ceramic, Nichrome
- d)Mica, ceramic
Correct answer is option 'D'. Can you explain this answer?

Insulating Materials Used in the Electric Toaster
The insulating materials used in the electric toaster are Mica, ceramic, and Nichrome. Let's understand the reasons behind the selection of these materials.
1. Mica:
- Mica is a natural insulator and has excellent thermal and electrical insulation properties.
- It can withstand high temperatures without getting damaged or conducting electricity.
- In the electric toaster, the heating element is wound separately on Mica sheets. These Mica sheets act as an insulating barrier between the heating element and the body of the toaster.
- The use of Mica ensures that the heat generated by the heating element is effectively transferred to the food being toasted, while preventing any electrical current from flowing through the body of the toaster.
2. Ceramic:
- Ceramic is another excellent insulating material used in the electric toaster.
- It is a non-metallic material that can withstand high temperatures and has good electrical insulation properties.
- Ceramic terminals are used to secure the heating element to the body of the toaster.
- These terminals provide a secure connection between the heating element and the electrical circuit without conducting electricity.
- The use of ceramic terminals ensures that the electrical current flows through the heating element and not through the body of the toaster.
3. Nichrome:
- While Nichrome is primarily used as the heating element in the electric toaster, it also contributes to insulation.
- Nichrome is an alloy made of 80% nickel and 20% chromium.
- It has a high resistivity, which means it offers significant resistance to the flow of electrical current.
- This resistivity allows the heating element to generate more heat when current passes through it.
- Additionally, Nichrome does not readily oxidize at high temperatures, ensuring the longevity of the heating element.
- The use of Nichrome in the heating element helps prevent any electrical current from flowing through the body of the toaster.
Conclusion:
In summary, the insulating materials used in the electric toaster include Mica, ceramic, and Nichrome. These materials provide effective insulation, both electrically and thermally, ensuring the safe and efficient operation of the toaster.
