5.10: Exponential Charge Flow
The voltage across the capacitor for the circuit in Figure 5.10.3 starts at some initial value, (V_{C,0}), decreases exponential with a time constant of (tau=RC), and reaches zero when the capacitor is fully discharged. For the resistor, the voltage is initially (-V_{C,0}) and approaches zero as the capacitor discharges, always following the loop rule so the …

Capacitance in AC Circuits
The voltage across the capacitor is therefore given as: V(t) ... Thus the resistive value of any parallel connected bleed resistor chosen will depend on how quickly the capacitor must discharge one power is removed, and the leakage current through the resistor when the capcitor is fully charged.

Capacitor Discharge
So if we discharge the capacitor for RC seconds, we can easily find out the fraction of charge left: V= V 0 e –RC/RC = V 0 e –1 = 0.37 V 0 . So, after RC seconds the voltage is 37 % of the original. This fact is used widely by electronic engineers. To increase the time taken for a discharge we can: Increase the resistance. Increase the ...
How do capacitors work?
Artwork: A dielectric increases the capacitance of a capacitor by reducing the electric field between its plates, so reducing the potential (voltage) of each plate. That means you can store more charge on the plates at the same voltage. The electric field in this capacitor runs from the positive plate on the left to the negative plate on the right.

How to Discharge a Capacitor? Using Bleeder Resistor, …
When we connect a DC Power Supply across the leads of a capacitor, the capacitor gradually accumulates charge between its plates until the voltage is equal to the supply voltage. Even if we disconnect the power supply, the capacitor continues to store the charge and in this way, a capacitor acts like a small battery.
How to Charge a Capacitor
In this case, the capacitor charges up to 9 volts, since it''s connected to a 9-volt battery. Many of the times while charging a capacitor, a resistor is used in series with the capacitor and voltage source to decrease the amount of current that flows through the capacitor, so that the capacitor isn''t damaged.

Capacitor discharge at lower voltages
Also, you seem to confuse yourself with capacitor voltage rating, which in this case is 400V (the maximum voltage that can be safely applied to the capacitor) and the voltage that is actually across the charged capacitor. For the calaculations of energy stored, the voltage across the capacitor is what you need to look for.

In your circuit, both switches must be closed to charge the capacitor. If either or both switches are opened the capacitor will not discharge but will retain the voltage it has when the switch is opened. Closing the both switches again will allow charging to continue until the capacitor voltage reaches 100V. Your circuit will not allow …

Supercapacitor | Capacitor Types | Capacitor Guide
While an ordinary electrostatic capacitor may have a high maximum operating voltage, the typical maximum charge voltage of a supercapacitor lies between 2.5 and 2.7 volts. Supercapacitors are polar devices, meaning they have to be connected to the circuit the right way, just like electrolyte capacitors.

How to Discharge a Capacitor
It is important to note that the best rating for low-voltage capacitors is a 5-watt 2kΩ resistor, while the best for high-voltage capacitors is a 5-watt 20kΩ resistor. The idea here is that the higher the resistance, the slower the transfer of energy from the capacitor, and the safer the discharge process is.
