Introduction:
When a capacitor is initially charged to a potential difference and then connected to a battery with opposite polarity, the capacitor discharges and the charge flows from the capacitor to the battery until the potential difference across the capacitor becomes zero. During this process, heat is generated due to the flow of current, and the final energy stored in the capacitor is determined by the potential difference across it.

Calculation:
Let the initial charge on the capacitor be Q and the capacitance be C. Therefore, the initial energy stored in the capacitor is given by:
E_initial = (1/2)Q^2/C

After connecting the capacitor to the battery, the charge on the capacitor will flow to the battery until the potential difference across the capacitor becomes zero. The final charge on the capacitor will be -Q and the potential difference across it will be -V. Therefore, the final energy stored in the capacitor is given by:
E_final = (1/2)(-Q)^2/C = (1/2)Q^2/C

Ratio of heat generated to the final energy stored:
The heat generated during the discharge of the capacitor is given by the equation:
H = E_initial - E_final
= (1/2)Q^2/C - (1/2)Q^2/C
= 0

Therefore, no heat is generated during the discharge of the capacitor.

The ratio of heat generated to the final energy stored is equal to zero divided by the final energy stored, which is zero divided by (1/2)Q^2/C. This ratio is zero.

Answer:
The ratio of heat generated to the final energy stored in the capacitor is 0.
