    Thanks a bunch Widell.  

    The
     “If 12 V draws 4 A, then you could pretend that it’s a 3 ohm resistive load.” 
    part was tripping me up when I was trying to use formulas found on internet.

    Most of this electronic circuitry stuff I can bumble through but obviously much of it still eludes me.

    Okay, considering that I did not phase the original question correctly.

    How about:
    What is the formula to figure capacitor size when a 2v drop over 500milliseconds is desired on disconnect of a circuit where 4A is being drawn from an original 12v power source?

    I knew that it was part of the reset but I was unsure about the current flow direction when a reset occurs.  I need to know which direction to insert my polarized capacitor.

    Does the negative lead connect to the USB connection or does it connect towards the ATMega?
