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.
What is meant by 80/20 Nichrome?
  • a)
    80% Chromium and 20% Nickel
  • b)
    80% Nickel and 20% Chromium
  • c)
    Purity 80%, Impurity 20%
  • d)
    It is a mixture of Chromium and Nickel
Correct answer is option 'B'. Can you explain this answer?

Explanation:


80/20 Nichrome:

  • 80/20 Nichrome is an alloy made up of 80% nickel and 20% chromium.

  • This alloy is commonly used for heating elements as it has a high resistivity and does not readily oxidize at high temperatures.


Electric Toaster:

  • The Electric Toaster designed by Small Industries Service Institute Takyelpat Industrial Estate Imphal operates at 220 volts A.C., single phase and is available in four different rated capacities of 600 W, 750 W, 1000 W and 1250 W.

  • The heating element of the toaster is made up of nichrome 80/20.

  • The nichrome 80/20 element is wound separately on Mica sheets and fitted with the body of the toaster with the help of ceramic terminals.
