This circuit will have a maximum current of I max = A: just after the switch is closed. The charge will start at its maximum value Q max = μC. At time t = s= RC: the current is = I max = A,
About Photovoltaic Energy StorageTo calculate capacitor discharge time the formula is: But because the current being sink from the capacitor is constant from highest voltage to zero volt, I think the capacitor should discharge faster as the capacitor voltage drops. right? simulate this circuit – Schematic created using CircuitLab
About Photovoltaic Energy StorageCR is known as the time constant – the larger it is, the longer the capacitor will take to discharge.) The units of the time constant are seconds. Why? ( F × W = C V-1 × V A-1, which simplifies to C A-1, and then again to C C-1 s, so just s) (Your specifications may require the relationship between the time constant and the halving time T ½ :

About Photovoltaic Energy StorageThe time it takes for a capacitor to discharge is 5T, where T is the time constant. What causes a capacitor to discharge? When the capacitor is fully charged and the electrical field from the source surrounding the capacitor goes down to zero, it causes an electron flow from the conductive plates of a capacitor to the circuit, which then causes ...
About Photovoltaic Energy Storage0.368 of its original value (at t = 0). is called the time constant for the exponential decay.
