Step 3) To begin charging the capacitor you need either a test light or a resistor. Often times these are included with the purchase of a capacitor but can be purchased separately if necessary. A) Using a …
If your line voltage is well-enough regulated that your zener solution would work, you could also just use a transformer to reduce your 311 V(peak) AC to 200 V(peak). Then use a half-rectifier and diode as you described to charge your capacitor. Another solution might work if you are only discharging the capacitor infrequently (every few minutes?).
In electrical engineering, a capacitor is a device that stores electrical energy by accumulating electric charges on two closely spaced surfaces that are insulated from each other. The capacitor was originally known as the condenser, [1] a term still encountered in a few compound names, such as the condenser microphone is a passive electronic …

Charging a Capacitor. When a battery is connected to a series resistor and capacitor, the initial current is high as the battery transports charge from one plate of the capacitor to the other.The charging current asymptotically approaches zero as the capacitor becomes charged up to the battery voltage.
Here you have a battery, a light bulb and a capacitor. If the capacitor is pretty big, what you will notice is that, when you connect the battery, the light bulb will light up as current flows from the battery to the capacitor to charge it up. The bulb will get progressively dimmer and finally go out once the capacitor reaches its capacity.
