Which engineering discipline is associated with designing electrical power systems?

• A. Mechanical engineers
• B. Electrical engineers
• C. Civil engineers
• D. Aerospace engineers

Answer: (B)

Electrical engineering is the field that designs electrical power systems. This discipline focuses on how electrical energy is generated, transmitted, distributed, and utilized, including the components that make up a power network—generators, transformers, switchgear, protective relays, and the control systems that manage flow of power. Engineers in this area analyze how electricity moves through grids, ensure reliability and safety, and integrate renewables, storage, and advanced power electronics.

Mechanical engineers work with machines and mechanical systems, civil engineers with structures and infrastructure like roads and buildings, and aerospace engineers with aircraft and spacecraft. None of those specialize in the electrical side of power systems, which is why the best fit for designing electrical power systems is electrical engineering.
