What You'll Learn
Power and energy engineering
Power engineering emerged as a critical discipline following Michael Faraday's discovery in 1831 that a change in magnetic flux induces an electromotive force in a wire loop, a principle known as electromagnetic induction, which underpins the operation of generators and transformers. In 1881, two electricians built the world's first power station in Godalming, England, employing waterwheels to generate alternating current. Subsequently, in 1882, Thomas Edison's company established the first steam-powered electric power station in New York City.
The late 19th century witnessed the commercialisation of electric power supply, leading to a “war of the currents” between Thomas Edison's direct current (DC) system and George Westinghouse's alternating current (AC) system, with AC ultimately prevailing as the standard. The spread of AC technology spurred the development of power systems, with thousands of networks established by the 1890s in the United States and Europe, primarily dedicated to electric lighting.
Today, power and energy engineering continues to evolve with emerging technologies such as smart grids, microgrids, and advanced energy storage systems like lithium-ion batteries and hydrogen fuel cells. Energy engineers play a pivotal role in shaping energy policies and regulations, leveraging their expertise to drive the transition to renewable energy sources and address global challenges posed by climate change.
Educational institutions like Purdue University Northwest offer bachelor's and master's degree programs in electrical engineering with a concentration in power and energy systems. These programs provide a blend of theoretical knowledge and hands-on laboratory experience, covering topics such as circuitry, mechanics, programming, thermodynamics, and project management.

Telecommunications
The field of telecommunications engineering is diverse and encompasses radio frequencies, satellite communications, fibre optics, and cellular networks. Electrical engineers in this field design the infrastructure that enables communication, from local Wi-Fi networks to global satellite systems. They are responsible for developing technology that facilitates communication over both short and long distances.
The first step in building any telecommunications system is designing a reliable and efficient network. Once the network is designed, electrical engineers are involved in the implementation process. They oversee the installation of components like antennas, cables, switches, and routers, ensuring the correct setup of each part. Testing is critical to identify potential issues and ensure the system's performance and reliability before going live.
Telecommunication networks require constant maintenance and upgrades to keep up with technological advancements and growing user demands. Electrical engineers monitor and troubleshoot these networks to ensure smooth and efficient operation. With the emergence of new technologies, engineers must implement changes to support faster speeds, increased capacity, and lower latency.
The security of telecommunications networks has become a top priority in the face of rising cyber threats. Electrical engineers in this field collaborate with cybersecurity experts to protect networks from hacking and data breaches. They implement security measures, encrypt data, set up firewalls, and regularly audit network security. The reliability of telecommunications systems is crucial as they are used for essential services such as emergency calls, military communication, and financial transactions.

Signal processing
Digital signal processing (DSP) is a critical application of signal processing in electrical engineering. DSP involves manipulating digital representations of signals to enhance, analyze, and transmit information. DSP is used in modern communication systems to remove noise, compress data, and ensure reliable information transmission across various communication channels, such as cellular and satellite communication. DSP is also used in image and video processing applications.
DSP is a mathematically intensive area, forming the core of digital signal processing. It involves incorporating several mathematical and computational algorithms into analog and digital signals to create a signal of more refined quality than the original. DSP is a competitive field in the job market, with high pay. However, some sources suggest that a broad knowledge of electrical engineering may not be necessary for a career in signal processing, as physics and math majors are often hired into these roles and can learn on the job.
