    Hello,

    From my calculations, the first option would give you an output voltage of 14.996V, and the second option would give you an output voltage of 15.017V. Both options will give you approximately a 15V output.

    Please let me know if you have any additional questions regarding the voltage divider.

    Best Regards,
