Difference Between Electrical & Electronics Engineering
These two Engineering fields may sound the same but in details, they are both worlds apart.
Based on the fact that both of these fields Electrical & Electronics Engineering deals with electricity makes them similar. But the reality is that the similarity ends right there.
Electrical Vs Electronics Engineering & Devices
Electrical Engineering deals with systems & devices that convert electrical energy into different forms of energy such as, motors converts it into mechanical energy, Heater converts into heat energy & so on. These devices are known as Electrical Devices.
On the other hand, Electronics Engineering deals with the systems & devices that control the flow of electrons based on the logic or signal provided by the user depending on the circumstance. One simple example of an Electronic device is a Transistor, which can either operate as a switch or an amplifier depending on the input signal.
The simplest difference between Electrical & Electronic devices is that the former does not possess the decision-making capabilities while Electronic Engineering & devices operate on decision-making capabilities.
For better understanding, a summarized comparison table of Electrical & Electronics Engineering is provided below.
|Deals with devices run on mostly Alternating Current||Deals with devices mostly run on Direct current|
|Does not have the capability of decision making||Works on decision-making capabilities to perform a specific task.|
|Deals with high AC voltage ratings ranging from 110-220 V (domestic) to 400 KV (in Industries)||Deals with voltage rating mostly from 3 to 12v DC|
|Deals with the electrical conductors made of Copper or Aluminum||Deals with the semiconductors such as Silicon & Germanium.|
|Deals with devices having a large physical size||Mostly deals with devices having small sizes|
|Deals with high current ratings which is considered dangerous||Mostly Deals with low current ratings which are considered safe to work.|
|Needs safety gear known as Personal Protection Equipment PPE||Does not require a special safety gear except for some cases.|
|Applications are Electrical energy transmission & conversion to mechanical Energy||Deals with processing & execution of specific response according to the input signal.|
Combination of Electrical & Electronics
Modern day appliances use both electrical and electronic circuitry to work more efficiently. For example, Industries use DC drives for speed control of DC motors. So a DC drive is an Electronic Device that regulates the speed of the DC motor while the DC motor is an Electrical device that converts the electrical energy into mechanical energy.
