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
