The value of the resistor and capacitor determines how long it takes for the capacitor to charge. The time it will take for the capacitor to completely discharge is 5RC, where R is the resistance and C is the capacitance. So if we have a 100μF capacitor and a 10KΩ resistor, it will discharge in approximately Τ= 5RC=5(10KΩ)(100μF)= 5 seconds.

The input op amp, in conjunction with the capacitor, presents that held value as the output via the driver op amp. As the input voltage increases further, the capacitor is charged to the higher voltage; if the input voltage decreases below the previous value, the voltage on the capacitor stays at the previous peak value.
Due to the fact that the current drawn from the capacitor depends on the voltage on the capacitor and the current drawn by the load, the above differentiation is not simple and requires an exact characterization of the switching current profile.
All we need to do is input our capacitor values of 10 and 220uF. We can type it like this on our calculators or into excel. But with manual calculation, we do 1 divided by 10 which is 0.1 and 1 divided by 220 which is 0.00454. We add these together to get 0.10454 and then 1 divided by this gives a total of 9.56uF.
