High silicon steel is commonly used in:
-
A.
aircraft frames
-
B.
automobile engines
-
C.
cooking utensils
-
D.
electrical transformers
Correct Answer:
D. electrical transformers
Explanation:
High silicon steel, also referred to as electrical or transformer steel, is a specialized ferrosilicon alloy engineered for its magnetic properties. It is primarily used in the construction of electrical transformers because the addition of silicon significantly increases the material's electrical resistivity and magnetic permeability. These characteristics are essential for reducing energy losses caused by eddy currents and hysteresis during the transmission and conversion of electrical power. While it is also used in motors and generators, its role in creating efficient magnetic cores for transformers is one of its most critical applications.
