It can hold a very large amount of charge and release the same over along period of time.
It depends in what circuit you are using it.
For power supply decoupling and regulation, bigger is better.
If you change the capactior value in a timing or tuned circuit, it will not behave as designed.
A: Any additional capacitor added in parallel will effectively increase to total capacitance by that value. Note that additional capacitor added must have the same voltage rating as the other
The main role of dielectrics in capacitors is to increase the value of capacitance of the capacitor.

The voltage marked on a capacitor is its MAXIMUM SAFE WORKING VOLTAGE. The capacitor will work in a circuit at any voltage lower than that, but it may fail at any higher voltage.
ideally there will not be any resistance to the capacitor,so at this condition it should not not discharge the stored energy. but practically small resistance will be there in the capacitor so the energy stored by the capacitor will be discharged through resistance.
capacitor always opposes the change in voltage , at beginning it shows the initial value and after sum time it charges and shows the maximum valve . Higher capacitor has higher voltage after some time , therefore it damages the equipment.
bigger capacitor value will make the discharge taking longer time and that is willmake the curve is closer to dc line which means the higher capacitor value will help to have a closer signal to the dc and reduce the ripple voltage
The two factors that determine the capacitive reactance of a capacitor are the frequency of the AC voltage applied to the capacitor and the capacitance value of the capacitor. At higher frequencies and with larger capacitance values, the capacitive reactance decreases.
You can see if the capacitor charges and discharges with an ohmmeter. You can check the value of the capacitor if the multimeter has the facility. With an ESR meter you can establish the value of the capacitor while in circuit.
To test an AC capacitor with a multimeter, first ensure the capacitor is discharged. Set the multimeter to the capacitance setting and touch the probes to the capacitor terminals. The reading should match the capacitor's rated value within a small margin of error. If the reading is significantly lower or higher, the capacitor may be faulty and needs to be replaced.
To test an AC capacitor, you can use a multimeter set to the capacitance setting. Disconnect the capacitor from the circuit, discharge it, and then connect the multimeter leads to the capacitor terminals. The reading should be close to the labeled capacitance value. If the reading is significantly lower or higher, the capacitor may be faulty.
I depends on the application for a rate amplifier the exact value is mandatory but for filtering that can vary greatly since every cap of that type has a very large -/+ tolerance YOU may install a greater voltage breakdown but never a less then the original
By testing capacitor tolerance
at full input, if the transistor is working, the value of capacitor will be 0.
If you apply a higher voltage to a capacitor than it is rated it could over heat and explode.
