Charge & Discharge Graphs | AQA A Level Physics Revision …
At the start of discharge, the current is large (but in the opposite direction to when it was charging) and gradually falls to zero; As a capacitor discharges, the current, p.d and charge all decrease exponentially. This means the rate at which the current, p.d or charge decreases is proportional to the amount of current, p.d or charge it has left

$begingroup$ thanks for the reply. In my application I have mentioned the maximum usage mostly the power will be less than that around 40W. Is there any chance I am able to use capacitors with higher voltage ratings eg:- 100mF caps with 16V ratings. since the voltage is 12V, they will charge up to 12V, according to the equation 1/2CV^2 …
