can i get admission on 45000 comedk uget rank for electronics in Nitte Meenakshi Institute of Technology banglore

NMIT accepts COMEDK UGET scores for admission to BE/ BTech courses. Since you specifically asked about Electronics, the closing ranks of the branch of all the 3 rounds have been specified below. These COMEDK UGET ranks are for the general category only. 

Considering your rank of 45000, you can get Electronics through counseling in the 3rd round. The chances are less so you can consider these branches as well with your rank.

• Civil Engineering
• Mechanical Engineering
• Aeronautics Engineering

It's better to keep all options open that be fixated on a particular branch.
