Electrical Engineering

Electrical Engineering is a branch of engineering studies that deals with electrically operated devices. This includes the study of electrical machines, power generation, power transmission and distribution, micro-controllers, sensors, etc. Subfields of electrical Engineering include Electronics Engineering, Telecommunication Engineering, Computer Engineering, Power Engineering, Computer Engineering, Power Engineering, Signal System Engineering, Instrumentation, robotics, etc.

What Does it Mean to be an Electrical Engineer?

An electrical engineer is a highly educated technician who designs and develops new types of electrical systems for both the public and private sectors. Electrical engineering involves solving complicated problems as they occur and testing equipment before any work is done. 

Electrical engineers have advanced knowledge of electricity, electromagnetism, electronics, and computers in general. What electrical engineers do is work on large and small-scale systems to make sure the systems are processing information and transmitting energy correctly. An electrical engineer might work with pocket-sized electronics one day and supercomputers the next.

How is electricity involved?

Electricity, in its basest definition, is a type of energy that is caused by negatively charged electrons. If electricity builds in one place, it is known as static electricity. When electricity moves from one place to another, it is labeled current electricity.

In electricity that moves, electrons must flow along closed pathways known as circuits, which generally consist of various components and wires. Most wires and parts are made of metals, including copper and aluminum, both of which are excellent electrical conductors. Metals conduct electricity because they are composed of an atomic structure that allows free electrons to flow smoothly through them.

You can further break down current electricity into two types that depend on how the current moves around a circuit. One variation, direct current (DC), moves around the circuit in the same direction. The second variation, alternating current (AC), constantly reverses its direction as it travels around the circuit.

In what industries do electrical engineers work?

Electrical engineering involves working with electrical systems like motor control and power generation, transmission, and distribution. This does not mean that the area of electrical engineers is confined to these but involved in diverse industries associated with various technologies. Some electrical engineers might work on household appliances while another engineer might work on telecommunication systems, or in electrical power stations.

Electrical engineers are not limited to industries that revolve around electricity. Instead, electrical engineers can work in mobile networking, finance, consulting, renewable energy, or nearly any other sector where problem-solving skills and logical thinking are required.

Electrical engineering is the backbone behind computers, tablets, and smartphones. Another typical example is providing electrical skills to the space program like deep-space communications, extraterrestrial GPS, imaging systems, and many other areas of space exploration. You will also find electrical engineers working on medical technology, including imaging machines like CT and MRI, blood pressure monitors, and ECG machines.

Electrical engineering deals directly with the technology of electricity. Most electrical engineers work with numerous different components and systems, ranging from microchips to large-scale power generators. Since its humble, albeit critical beginnings with the creation of batteries, electrical engineering has advanced to the point that the technology industry depends mostly on the work that electrical engineers perform. Without electrical engineers, there would be no light bulbs, radios, or televisions, let alone computers. Electrical engineering has branched out to different categories over the years, including areas like radio frequency, telecommunications, and digital circuits. 

Electrical engineers are responsible for designing, developing, and testing electrical equipment and devices that produce conduct, or run-off electricity. Modern electrical engineers work on electrical appliances that utilize conductors, coils, magnets, inductors, etc. Most electrical devices run on the basic components that electrical engineers use in everyday practice. These devices include everything from power stations to the microprocessors inside your phone.

The advancement of what electrical engineers do now and in the future is extraordinary and continually growing.

How do electrical engineers work with electricity and electronics?

A subcategory of electrical engineering is electronic engineering. Electronic engineering applies the basic tenants of electrical engineering of creating, building, and testing electronic circuits. Most electronic circuits use a combination of components like resistors, capacitors, inductors, diodes, and transistors to develop a specific type of functionality.

Before the Second World War, electrical engineers in the electronics field worked solely on radios. In modern times, the field has grown to encompass, televisions, audio systems, microprocessors, and computers. Before the integrated circuit was first developed, most electronic circuits were built out of pieces that were easily handled and manipulated by humans. These circuits required too much space and power and were mostly dropped for integrated circuits in 1959. Integrated circuits are built of many small electrical components and are usually as little as a coin. Without integrated circuits, we would not have computers and other electronic devices that rely on integrated circuits to run.

What electrical engineers do, in this arena, is focused on the appliances and devices that use electricity, many of which average citizens use every day like smartphones and computers. 

How is electricity utilized in electrical engineering?

Current electricity moves electrical energy from one to another; an example of current electricity is a lightning bolt. Current electricity is used to power all electrical appliances developed, built, and tested by electrical engineers. This includes everything from washing machines to MP3 players. 

In electrical circuits, there is a closed path or loop through which an electric current flows. Electrical engineers make a circuit by linking various components with wire cables. What electrical engineers do is use current electricity and electrical circuits to build electronic devices that improve lives and provide much-needed help and entertainment.

“Can I choose a career in Electrical engineering?”

Electrical engineering is an advanced career choice that involves working directly with electricity, building electronics, and working on electrical circuits. Without electrical engineers, our current world of high-tech electronics would not exist.

From the invention of batteries and the light bulb to today’s creation of MP3 players and smartphones, electrical engineers have been around since the 19th century. They are a vital part of our technologically advanced world.
