    what is the Effective emf of 2 cells with zero internal resistance connected in parallel
    (E1>E2)

    Good morning mksrpillai, welcome to Physics Forums.

    All cells have internal resistance.

    It is not a good idea to try to use division-by-zero scenarios as anything other than to show how pointless division-by-zero scenarios are.

    The concept of internal resistance applies to all electrical sources.

    If two cells of equal emf s are connected in parallel then the effective emf is equal to the emf of any one of the cells.
    If two cells of different emf are connected in parallel then the effective emf is equal to the
    emf of the cell which is having greater emf. so in ur case E1is the effective emf.
