The same question was once asked in edaboard.com...Hope this link will be helpful to you http://www.edaboard.com/thread222232.html

Hope this site would help you

The link Tapas Pattnaik provided is also very useful for finding the values.

The hyperphysics link is truely awesome to calculate any parameter for capacitors. I honestly don't think that there is any simple formula to calculate a capacitor's discharging current. You may have to follow a some procedures and use some formulas to calculate some parameters before calculating discharging current. Correct me if I am wrong, I need to find out Voltage at time=0, Voltage at time=infinity and Voltage at time=t. Then, use the formula I = C*dV/dt.

i=c*dv/d so theoretical answer is infinite current. In practice, it is lesser than Infinity and one cant have infinitely fast changing currents in a finite inductor either without developing infinite voltages. Depends on material, dielectric relaxation time, parasitic inductance of leads etc & other material properties of solids, amorphous materials, highly non linear types of stuff with voltage, temperature, aging and host of details.. Best is always to follow manufacturers guidelines and be safe.
