Electronics Engineering or Electronic Engineering is a branch of engineering which deals with the utilization of active, passive and electromechanical electronic components to make a predefined specific design.
1. The active electronic components are:
· Amplifiers
· Transistors
· Semiconductor devices
· Integrated Circuits (ICs)
· Most of the power generating devices – Battery, fuel cell, photo voltaic etc.
· Vacuum tubes
· Display devices like LCD, LED etc.
· Semiconductors
· Optoelectronic devices
2. The Passive electronic components are:
· Resistors
· Variable resistors
· Capacitors
· Inductive devices – inductor, coil, chok
· Sensors
· Protection devices
· Antennas
· Switches etc.
3. Electromechanical components
In my experience and having these all the knowledge above, Electronics Engineering is a tough Engineering among other Engineering.
