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.
- Modern Engineering
- Educational opportunities
- 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.
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.
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.
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.

- 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.
- 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.
- The electrical devices mostly works on the alternating current whereas the electronics devices uses the direct current.
- The electrical devices uses the high voltages whereas the electronics devices work on low voltages.
- The power consumption in electrical devices is more as compared to the electronics devices, because of the less voltage they use.
- The conductivity of the electrical devices is higher then the electronics devices.
- The electrical devices can’t able to manipulate the data whereas the electronic devices are able to manipulate the data.
- 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.
- 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.
