Electronics Engineering

Electronics and communication engineering, or electronic engineering, is an engineering discipline where non-linear and active electrical components such as electron tubes and semiconductor devices especially transistors, diodes, and integrated circuits, which are utilized to design electric circuits, important devices, and systems typically also including passive electrical components and based on printed circuit boards.
This is a broad engineering field that covers analog electronics, digital electronics- both of them dealing with transmission of the signal, consumer electronics, and embedded systems and power electronics. Electronics engineering deals with implementation of applications, principles, and algorithms developed within many related fields, for example, solid-state physics, radio engineering, telecommunications, control systems, signal processing, systems engineering, computer engineering, instrumentation engineering, electric power control, robotics, and many others.
This area involves the transmission of information across channels such as a coax cable, optical fiber or free space. You can work on designing equipment such as routers, switches, multiplexers and electronic switching systems, copper telephone facilities and fiber optics. It develops everyday devices such as transistors, integrated circuits, and printed circuit boards (PCBs) which can be used in computers, MP3 players, cell phones, television to name a few. The discipline deals with electronic devices and software interfaces. The applications are far reaching, right from the indoors of the house to industries. The tasks of the Electronics and Communication engineers are to direct, control and test produce process a well as to ensure safety, installation, and functioning of the various mechanisms.
All the best.

Hello Shubham,
Scope is a very vague word.
If you want to know what are your opportunities after studying EEE, that would be a better question. I would say it depends on so many other factors that this question can't be answered well. The college where you study is of utmost importance. Your willingness to pursue higher studies (MS, M.Tech) will decide what you can do in the field.
If you are thinking job scenario wise, any engineering degree from a good college is good enough to get a job (Might not be in EEE) . EEE jobs are lesser anywhere and you will need to be in the top to get them. Higher studies increases chances that you can pursue the field as many jobs in EEE need specialization.
All the best.
