Earthed line in Split power supply in op-amp

  1. What is the work of the earthed line with zero potential between two power sources in the op-amp.

    What is the normal function of earth wire except for preventing shock?

    @Miraj -- can you post an equivalent schematic diagram of a typical opamp, like an LM741 or similar? That will make it easier for us to discuss your question.
