How do I know the maximum voltage that a capacitor releases?
When disconnected from the circuit, the capacitors voltage is equal or lower to the previously applied voltage. A capacitor can store electric energy. It depends on the load how fast a capacitor discharges when connected to that load. (T = R * C) The voltage rating just specifies the maximum voltage that should be applied to the capacitor.

$begingroup$ It only really applies to ripple that is small relative to the DC voltage. The assumption is that the conduction period of the diode is small and the current through the load is essentially constant. Your example does not meet either of those constraints. Try increasing the capacitor to 10uF and look at it then. $endgroup$
