Electrical engineers apply physics to design and develop electrical systems and devices
Electrical engineering is a field that applies physics and mathematics to design, develop, test, and supervise the manufacturing of electrical systems and devices. Electrical engineers work on a variety of projects, from power plants and power grids to microchips, computers, smartphones, and other electronic devices. They also design electrical systems for automobiles and aircraft.
The work of electrical engineers involves a practical understanding of physics and mathematics to create products that make electrons do useful things. For example, electrical engineers may work on the design and development of transformers, electric generators, electric motors, and power electronics. They also work on power distribution and instrumentation, such as designing devices to measure physical quantities like pressure, flow, and temperature.
The development of radio technology and electronics in the 19th century was a significant application of physics in electrical engineering. Scientists and inventors like Heinrich Hertz and Guglielmo Marconi contributed to the development of radio waves and methods for transmitting and detecting them. Similarly, the work of James Clerk Maxwell and Charles Steinmetz on alternating current engineering laid the theoretical basis for AC power systems.
Today, electrical engineers continue to play a crucial role in developing advanced technologies, including renewable energy systems, robotics, and autonomous systems. With the increasing demand for renewable energy, electrical engineers are in high demand for designing and managing electrical power systems.
Electrical engineering is closely related to physics, and physicists with a background in building and designing things can become electrical engineers. Electrical engineers typically need at least a bachelor's degree in electrical engineering, electronics engineering, or a related engineering field. However, employers also value practical experience, such as internships or participation in cooperative engineering programs.

Power and energy engineering focuses on the generation, transmission, and distribution of electricity
Power and energy engineering, a subfield of electrical engineering, focuses on the generation, transmission, distribution, and utilization of electricity. This field covers critical infrastructure such as power plants, electric grids, and energy storage systems, ensuring the efficient and reliable delivery of energy.
The generation of electricity involves the selection, design, and construction of facilities that convert energy from primary forms to electric power. This includes power plants and electric grids, with the latter connecting various generators to users of their energy. Users can purchase electricity from the grid, avoiding the costly process of generating their own power.
Electric power transmission involves the engineering of high-voltage transmission lines and substation facilities to interface with generation and distribution systems. Transmission lines are typically tall, spanning long distances, and carrying multiple wires. The transmission of electricity may be in the form of direct current (DC) or alternating current (AC). The rivalry between Thomas Edison and Westinghouse in the US, known as the "war of the currents," showcased the debate over the superiority of direct or alternating current for transmission. Ultimately, alternating current became the standard for long-distance power transmission due to its efficiency and ability to transmit power over long distances using transformers.
The distribution system marks the final stage of the delivery process, supplying electricity at voltages suitable for residential and corporate use. This electricity powers appliances and other essential devices.
Power and energy engineering also involves the design of related devices, such as transformers, electric generators, and electric motors.
Emerging technologies in this field include smart grids, microgrids, advanced energy storage systems, and renewable energy sources. Energy engineers play a crucial role in shaping energy policies and regulations, ensuring energy efficiency, and reducing carbon footprints.
Physicists, including those with a background in electrical engineering, contribute to the development of power and energy engineering. Job titles for graduate physicists include engineering physicists, who may work in various sectors such as academia, government, and industry.

A physics degree is a prerequisite for becoming an electrical engineer
Electrical engineering is a specific application of the general principles of physics. A physics degree is not mandatory to become an electrical engineer, but it does provide a strong foundation for a career in engineering. It imparts essential problem-solving and analytical skills, which are highly valued in the field of engineering.
Students pursuing a physics degree study classical mechanics, thermodynamics, electromagnetism, quantum mechanics, atoms, molecules, and statistics. This knowledge helps future electrical engineers understand the constraints of a problem and devise practical solutions. Physics graduates may need to take additional steps to transition into electrical engineering, such as selecting electives or additional coursework related to electrical engineering.
Some universities offer dual-degree programs, allowing students to graduate with a Bachelor of Science in physics and a Bachelor of Science in engineering or electrical engineering. Alternatively, students can pursue a sequential program, first earning an undergraduate degree in physics and then a master's degree in an engineering specialty.
Electrical engineering is a broad field with various specializations, such as power and energy engineering, which focuses on electricity generation, transmission, and distribution, as well as the design of related devices like transformers and electric motors.
