Electronics/Capacitors
Charging creates a charge imbalance between the two plates and creates a reverse voltage that stops the capacitor from charging. As a result, when capacitors are first connected to voltage, charge flows only to stop as the capacitor becomes charged. When a capacitor is charged, current stops flowing and it becomes …

Charging a low-voltage high-C capacitor. Efficiently
Putting the 2.2V zener in parallel with the capacitor does not cut into the charging efficiency at all — the zener doesn''t conduct at all until the capacitor is fully charged. But once it does conduct, it needs to absorb all of the energy coming from the dynamo, so make sure it''s suitably rated.
What happens if I connect a low voltage rated capacitor to a high voltage?
For a capacitor, one of the limits is keeping the voltage low enough that the capacitor dielectric stays intact. As you increase the terminal voltage, the electric stress increases across the dielectric, and eventually, it breaks down. When that happens, you don''t have a capacitor any more.
Charging a low-voltage high-C capacitor. Efficiently
When the caps aren''t charged, then the current/difficulty of turning/torque will be high even at low speeds/voltages. Why is this? Consider the law of conservation of energy.
