I like electric and mechanics both ? Is there is an branch in engineering for these both combined, please suggest me.

Yes! there is a stream known as mechatronics which along with concept of electrical also uses mechanical laws.Mechatronics is a synergistic combination of precision engineering, electronic control and mechanic systems. It is the science, that exists at the interface among the other five disciplines:

there is a new branch that is mixture of 4 or 5 branch but it is not available in iit
