6. Special Materials

Electrical engineering is a field that deals with the study and application of electricity, electronics, and electromagnetism. The field of electrical engineering is vast and diverse, and it encompasses a wide range of subfields, including power generation, transmission, and distribution, as well as the design and development of electrical systems and devices. One of the fundamental aspects of electrical engineering is the study of electrical engineering materials, which are used to design and develop electrical systems and devices.
