Electronics and Electrical engineering are two well known fields of the engineering and quite similar from each other . So there is always a debate that which of them is better from other one . Here the term Electronics vs Electrical Engineering comes and in this article we discuss in detail about the various factors related to Electronics vs Electrical engineering.

electronics vs electrical engineering

Here we not gonna talk about which one is the best Electrical or Electronics, here we just discuss the various factors related to these two fields, which leads to start a debate on electronics vs electrical engineering . At the end of this article some of you find electronics is the best and some will say electrical is. It all depend on the interests, every person has its own. so its all upon you which one you find interesting .

Electronics vs Electrical Engineering

Both of the fields are very vast, so explain Electronics vs Electrical Engineering on the basis of various factors which will be helpful to understand them briefly.

  1. History
  2. Modern Engineering
  3. Educational opportunities
  4. Scope
  5. Major differences

1. History – Electronics vs Electrical Engineering

First we talk about the history of Electronics then later about electrical. History plays the important role in electronics vs electrical engineering

History of Electronics Engineering

The roots of electronics were setup back in 1897 – It all starts when John Ambrose Fleming invented the vacuum diode ,  after that, a vacuum triode was implemented by Lee De Forest to amplify electrical signals. This led to the introduction of tetrode and pentode tubes that dominated the world until the World War II.

Sir John Ambrose Fleming

But there is an interesting fact that Sir John Ambrose Fleming is known as Electrical engineer not an Electronics engineer. So , you can feel now that Electronics vs Electrical engineering is not only a current debate.

Then in 1948, the transistor era began with the invention of junction transistor. Even though, this particular invention got a Nobel Prize

Later these junction transistor replaced with a bulky vacuum tube that would consume high power for its operation. The use of germanium and silicon semiconductor materials made theses transistor gain the popularity and wide-acceptance usage in different electronic circuits.

The years 1958 to 1975 marked the introduction of IC with enlarged capabilities of over several thousand components on a single chip such as small-scale integration, medium-large scale and very-large scale integration ICs.

Digital integrated circuits were yet another robust IC development that changed the overall architecture of computers. These ICs were developed with Transistor-transistor logic (TTL), integrated injection logic (I2L) and emitter coupled logic (ECL) technologies.

electronics vs electrical engineering

All these radical changes in all these components led to the introduction of microprocessor in 1969 by Intel. Soon after, the analog integrated circuits were developed that introduced an operational amplifier for an analog signal processing.

History of Electrical Engineering

The first practical application of electricity was the telegraph, invented by Samuel F.B. Morse in 1837. The need for electrical engineers was not felt until some 40 years later, upon the invention of the telephone (1876) by Alexander Graham Bell.

Thomas Edison

The incandescent lamp (1878) by Thomas A. Edison. These devices and Edison’s first central generating plant, in New York City (1882), created a large demand for people trained to work with electricity.

 Hendrik Antoon Lorentz of the Netherlands postulated the electron theory of electrical charge in 1892, and in 1897 J.J. Thomson of England showed that thermionic emission was indeed caused by negatively charged particles (electrons).

In 1930 the term electronics was introduced to embrace radio and the industrial applications of electron tubes. Since 1947, when the transistor was invented by John Bardeen, Walter H. Brattain, and William B. Shockley,

In 1938, dated to about 250 BCE and called the Baghdad Battery, resembles a galvanic cell and is claimed by some to have been used for electroplating in Mesopotamia, although there is no evidence for this. Which leads that may be the history of electrical engineering is way back then be thought.

Modern Engineering – Electronics vs Electrical engineering

First we talk about electronics and later then electrical modern engineering. Modern engineering totally change the angle of electronics vs electrical engineering.

Modern Electronics engineering

Defination – Electronic engineering is an electrical engineering discipline which utilizes nonlinear and active electrical components to design electronic circuits, devices, integrated circuits and their systems. The discipline typically also designs passive electrical components, usually based on printed circuit boards.

In the field of electronic engineering, engineers design and test circuits that use the electromagnetic properties of electrical components such as resistors, capacitors, inductors, diodes and transistors to achieve a particular functionality.

Electronics is a subfield within the wider electrical engineering academic subject but denotes a broad engineering field that covers subfields such as analog electronics, digital electronics, consumer electronics, embedded systems and power electronics.

Integrated circuits, FPGAs and other electrical components can then be assembled on printed circuit boards to form more complicated circuits. Today, printed circuit boards are found in most electronic devices including televisions, computers , audio players and air conditioner

Modern Electrical Engineering

Definition – Electrical engineering is an engineering discipline concerned with the study, design and application of equipment, devices and systems which use electricity, electronics, and electromagnetism.

There is a wide range of fields in which electrical engineering is divided like computer engineering, power engineering, telecommunications, radio-frequency engineering, signal processing, instrumentation, and electronics.

Electrical circuit

Electrical engineering overlap with other engineering branches, spanning a huge number of specializations including hardware engineering, power electronics, electromagnetics and waves, microwave engineering, nanotechnology, electrochemistry, renewable energies, mechatronics, and electrical materials science.

Electrical engineering has many subdisciplines, the most common of which are

  • Power – This branch of engineering deals with the generation, transmission, and distribution of electricity as well as the design of a range of related devices. These include transformers, electric generators, electric motors, high voltage engineering, and power electronics. In many regions of the world, governments maintain an electrical network called a power grid
  • Control –  This branch of engineering focuses on the modeling of a diverse range of dynamic systems and the design of controllers that will cause these systems to behave in the desired manner. To implement such controllers, electrical engineers may use electronic circuits, digital signal processors, microcontrollers,
  • Signal processing – This branch deals with the analysis and manipulation of signals. Signals can be either analog, in which case the signal varies continuously according to the information, or digital, in which case the signal varies according to a series of discrete values representing the information.

3. Educational opportunities – Electronics vs Electrical Engineering

First we talk about the electronics engineering then electrical engineering educational opportunities. Educational view is an important factor in electronics vs electrical engineering

Educational opportunities of Electronics engineering

Electronics engineers typically possess an academic degree with a major in electronic engineering. The length of study for such a degree is usually three or four years and the completed degree may be designated as a Bachelor of Engineering, Bachelor of Science, Bachelor of Applied Science, or Bachelor of Technology depending upon the university

The Institute of Electrical and Electronics Engineers (IEEE) is one of the most famous and influential organizations for electronics engineers based in the US. At international level, the International Electrotechnical Commission (IEC) prepares standards for electronic engineering, developed through consensus and thanks to the work of 20,000 experts from 173 countries worldwide.

Some electronics engineers also pursue a postgraduate degree such as a Master of Science, Doctor of Philosophy in Engineering, or an Engineering Doctorate. The master’s degree is being introduced in some European and American Universities as a first degree but does’t apply on the rest of the globe

A degree in electronics generally covering units like physics, chemistry, mathematics, project management and specific topics in electrical engineering and some about information technology. Initially, such topics cover most, if not all, of the sub-fields of electronic engineering. 

Most electronic engineers will be able to understand basic circuit theory, the theories employed by engineers generally depend upon the work they do. For example, quantum mechanics and solid state physics might be relevant to an engineer working on VLSI but are largely irrelevant to engineers working with embedded systems.

Educational opportunities of Electrical engineering

Electrical engineers typically hold a degree in electrical engineering or electronic engineering. Practising engineers may have professional certification and be members of a professional body or an international standards organization.

The IEC prepares international standards for electrical engineering, developed through consensus, thanks to the work of 20,000 electrotechnical experts, coming from 17 countries worldwide.

Electrical engineers typically possess an academic degree with a major in electrical engineering, electronics engineering, electrical engineering technology, or electrical and electronic engineering. The same fundamental principles are taught in all programs, though emphasis may vary according to title

The bachelor’s degree generally includes units covering physics, mathematics, computer science, project management, and a variety of topics in electrical engineering.

Some electrical engineers choose to study for a postgraduate degree such as a Master of Engineering/Master of Science (MEng/MSc), a Master of Engineering Management, a Doctor of Philosophy (PhD) in Engineering, an Engineering Doctorate (Eng.D.), or an Engineer’s degree.

In most countries, a bachelor’s degree in engineering represents the first step towards professional certification and the degree program itself is certified by a professional body. After completing a certified degree program the engineer must satisfy a range of requirements (including work experience requirements) before being certified

  1. The electrical device changes the current into one for to another form of energy like heat, light,radiations etc. whereas the electronic device controls the movement of electrons for performing the various operation.
  2. The electrical devices use copper and aluminium wires for the flow of electrical current in electrical devices whereas the electronics devices use the semiconductor materials in circuits.
  3. The electrical devices mostly works on the alternating current whereas the electronics devices uses the direct current.
  4. The electrical devices uses the high voltages whereas the electronics devices work on low voltages.
  5. The power consumption in electrical devices is more as compared to the electronics devices, because of the less voltage they use.
  6. The conductivity of the electrical devices is higher then the electronics devices.
  7. The electrical devices can’t able to manipulate the data whereas the electronic devices are able to manipulate the data.
  8. The electrical device directly works on the current due to which it gives the quick response.The electrons are the only moving charge of the electronic device and hence their response time is less.
  9. The electrical device is heavy and larger in size and hence requires more space whereas the electronics components are very smaller in size and placed on the single chip or we can say it requires very less space to carry them.
  10. The electrical device is more dangerous as compared to the electronic device because in electric devices heavy short circuit occurs because of the fault which is very dangerous for life while in electronics circuits little sparks were happen.
  11. The fan, transformer, motor, generators are the examples of the electrical device whereas the transistor,microprocessor, thyristor, microcontroller are the examples of the electronics device.
