Hello dear..,

It's bit complex question,

Still I'll try to give fair answer.

First understand the subdomains of Electrical

POWER Electronics

Power Drives

Power system

Control system

Image processing

VLSI design

Mechtronics

High voltage engineering

Renewable energy

Communication

Power system

Machine Designs

These are major subdomains .

Each having it's own area and future scope so it's difficult to compare

You just go based on your own interest

Hope you're clear

Thank you
