Electrical engineering is a vast and diverse discipline covering almost every area of our daily lives involving electricity. From designing city power grids to making circuit boards with tiny pieces that the human eye can barely see, electrical engineers are responsible for making the world go round. They are, quite literally, what powers the global economy. 

If you are seeking an electrical engineer, you might be wondering, what are some interview questions for an electrical engineer? Before jumping straight into hiring an electrical engineer, it might be helpful to examine the different types in a bit more detail. 

What Are the Different Specializations of Electrical Engineering?

Electrical engineering is divided down into power, electronics, control systems, signal processing, and telecommunications engineering. Each of these groups breaks down into several subgroups of their own. To keep it brief, we’ll just cover these main areas.

Power Engineering

This field is concerned with generating power and how the power gets from point A to point B, also known as transmission. Without power engineers, our biggest and brightest cities would become dark each night, and we wouldn’t be able to exist in the modern comfort to which we’ve become so accustomed. 

Some examples of power engineering are as follows:

  • Designing power generation plants such as nuclear or hydroelectric
  • Planning city electrical grids to ensure optimal distribution of power throughout a municipality
  • Drawing power wiring schematics for large industrial buildings
  • Designing battery and power systems for portable equipment

Electronics Engineering

This electrical engineering discipline focuses on the circuitry and power supply in many products we use daily. Major manufacturers worldwide employ thousands of electronics engineers to help design every conceivable electronic device you could imagine. 

Here are a few examples we might see in the real world:

  • Designing circuit boards for a remote control
  • Designing plans for satellites
  • Ensuring circuit boards have adequate systems in place to process data as necessary
  • Microchip design and fabrication for use in everyday electronics

Control Systems Engineering

Control systems are pretty self-explanatory. These are the systems that control our lights, fans, air conditioning, security and fire alarms, and all manner of other systems that need constant monitoring or control. Below, you’ll find some examples of what a control systems engineer might do:

  • Designing thermostats for use in your home heating and cooling system
  • Working on boxes designed to act as the central hub of a building’s control systems
  • Validating that a data center has the correct power, air cooling, and fire alarm systems connected to a single control point where the manager can oversee everything

Signal Processing Engineering

A person wants to send a text message to a friend. How does the phone send the signal, and where does it go? How does the signal go to the correct phone and not the phone of a random guy nearby? Hello, signal processing! 

Signal processing allows calls to be sent and received seamlessly without manually directing them. Some examples of signals processing engineering might be:

  • Writing algorithms to capture incoming signals and process them to determine their origin and destination
  • Programming artificial intelligence (AI) and other systems to route signals to their correct destinations
  • Designing systems to overcome difficulties in sending signals such as distance, storms, or intentional jamming by hostile entities
  • Planning encryption for seamless and secure end-to-end transmission of messages and signals around the world

Telecommunications Engineering

Telecommunications engineering is related to all the technology and infrastructure behind the scenes that allow the signals to travel to where they need to go to keep our digitally connected world moving. 

Telecommunications engineers make it all possible, whether it’s a phone call to your grandmother or a text message to your best friend about your Saturday night plans. 

Here are some things a telecommunications engineer might be doing on a day to day basis:

  • Antenna design and testing for radio-controlled devices
  • Designing receivers to capture and process the collected data 
  • Microphone designs that filter out background noise so you can hear the speaker without being distracted by any ambient sounds
  • Working with satellite companies to enhance coverage and distribution of phone and internet services worldwide. 

Final Thoughts

As you can see, an electrical engineer might specialize in one of many disciplines. The fields are so vastly different and specialized that there is not a single electrical engineer out there that could jump into any of these roles and be ready to hit the ground running on day one. There are years of education, training, and hands-on experience required to become a successful electrical engineer in just one of the areas we’ve listed above. From electrical engineers to ea programmers, you can find the expert you need on Guru.
