Yes, you can. It is a nice college. You can also try Haldia Institute of Technology.

In short term? For holding the degree of electrical engineering after Diploma in civil engineering must invest 3 more years with recognised board which will give you a valid degree worldwide. There are few course in the market which may specialise you in the subjects like course from NPTI but it will definitely not give you a degree in electrical engineering. Hope this helps.
