Hello aspirant, 

Electrical engineering branches is one of the oldest and core branches of engineering. It deals with with concepts related to electricity, generators, motors, and major electrical instruments, etc.

Science stream students who have passed 12th board examination with PCM are eligible to pursue this course.

Qualifies electrical engineers are always in demand, since most industries use electrical instruments and electricity. Jobs are available both in government and private sector.

Coming to the mechanical engineering branch, it is the evergreen branch among all the branches.

They deal with the concepts of mechanics, thermodynamics, robotics, kinematics, structural mechanics, fluid mechanics, power sector, refrigeration, air conditioning sector and aerospace. There is a great scope of mechanical engineering now-a-days. It is expanding beyond its boundaries and more of interdisciplinary in nature. It is one of the oldest branches of engineering. This field of engineering is the broadest of all engineering fields, job prospects on offer for skilled engineer are plenty and unending. They can find employment in both government as well as private sector. Mechanical engineers are required to design, test, manufacture, install, operate and maintain a wide array of machines and mechanical systems that are used in industries. There is a great scope of job avenues for mechanical engineers in India.

So, both the branches are best in itself but first you need to differentiate between them thoroughly. You need to seek and find your interest whether it is by hook or crook. 

Hope it helps. 

Good luck!
