Also, 8 VAC rectified has 11V peak voltage which gets charged to the capacitor. Otherwise there is a simple formula for calculating the capcitor value. Q=I×t and Q=C×U. You just need to know the maximum current and allowable ripple voltage and mains ripple frequency after full bridge rectifier is 100 Hz.
The capacitors help to fill in the gaps in the rectified voltage. While the voltage reaches its highest values, the capacitor is charged. When it drops below a certain level, it discharges. However, due to the rectifier circuit, it cannot send the charge back to the voltage source, but discharges it via the consumer.
Generally you don't supply power via resistor divider but a regulator. And the LED is upside down as well. Also, 8 VAC rectified has 11V peak voltage which gets charged to the capacitor. Otherwise there is a simple formula for calculating the capcitor value. Q=I×t and Q=C×U.

The idea is finding the degree of smoothing effect of the capacitor by specifying tolerable amount of the voltage variation on the load. The input variables to the formula are: a. Input AC voltage, b. Load current, c. The ripple tolerance on the load.
As the rectified voltage rapidly declines and falls away from its peak at 90 degrees, it also falls away from the capacitor voltage and the capacitor is then supplying all of the current to the load.
Without smoothing capacitors the fullwave rectified DC will have the same RMS value as the AC waveform (ignoring losses in the rectifier). Figure 2. Smoothing capacitor …

It works by assuming that the capacitor supplies current to the load approximately 70% of the cycle—the remaining 30% is supplied directly by the rectified voltage and during this period the capacitor is charged as well.
