    In which configuration Operational amplifier will dissipate more power and it will get hot. Its a part of my project so if you can help pe please suggest me some circuits for dual supply opamp.

    The power dissipation of an op amp (besides its intrinsic operating current) is determined by the output load current, output voltage, and power supply voltage. It's otherwise little affected by the configuration.

    The configuration depends upon what you want the op amp to do, which you haven't stated.

    How can we possibly suggest dual supply op amp circuits for your project when you have given absolutely no clue as to what your project is or what you want this opamp circuit to accomplish?

    Here are some circuits. You provide the dual supply.
