Which of the following is an Electrical Engineering discipline?

Power Systems is indeed a discipline within Electrical Engineering that focuses on the generation, transmission, distribution, and utilization of electrical energy. This field encompasses the design, operation, and maintenance of electrical grids and infrastructure to ensure the reliable and efficient delivery of electricity. It is critical for supporting modern society's energy needs and addresses challenges such as energy efficiency, renewable energy integration, and smart grid technologies.

The other disciplines listed, while crucial in their respective areas, do not fall under Electrical Engineering. Instrumentation Engineering generally involves the design and use of instruments for measurement and control in various industries, which intersects with electrical principles but is more specialized. Structural Engineering is a branch of civil engineering that deals with the design and analysis of structures like buildings and bridges. Ceramics Engineering focuses on the processing and properties of ceramic materials, which is a distinct field from electrical engineering. Each of these fields has its own unique principles and applications that do not specifically pertain to the core functions and studies of Electrical Engineering.
