Q1:

Silicon percentage in silicon steel used for electrical equipments is about

A 1

B 4.0

C 8

D 14

ANS:B - 4.0

Silicon steel, also known as electrical steel or transformer steel, typically contains a silicon percentage of around 3.2% to 4.0%. This specific silicon content is chosen for its beneficial electrical properties, including high electrical resistivity and low hysteresis loss, making it ideal for use in electrical equipment such as transformers, electric motors, and generators. Therefore, the correct option from the provided choices is 4.0%.
