When a capacitor is fully charged does it block AC or DC?
pairofstrings said:i think it should block DC, and allow AC if the circuit has a path to discharge the capacitor.
pairofstrings said:By 'fully charged' I think it means that, more electrical energy cannot be accommodated beyond it's maximum point.

pairofstrings said:The maximum point is the point beyond which capacitor cannot be charged further.
I don't know why it happens that -
Capacitors can never get fully charged and they can never be fully discharged which is an immense point of interest.
Does anybody have any explanation for this phenomenon?

A capacitor is an electronic component that stores electrical energy in the form of an electric field. It is made up of two conductive plates separated by an insulating material, called a dielectric.
A capacitor becomes fully charged when the voltage across its plates reaches the same voltage as the source connected to it. This can occur when the capacitor is connected to a power supply or when it is charged through a circuit.
When a capacitor is fully charged, it has reached its maximum voltage and can no longer store any more electrical energy. The electric field between the plates is at its maximum, and any further charging will cause the capacitor to break down or discharge.
The time it takes for a capacitor to become fully charged depends on its capacitance, the voltage of the power supply, and the resistance in the circuit. Generally, it takes 5 time constants (5RC) for a capacitor to become fully charged, where R is the resistance in the circuit and C is the capacitance of the capacitor.
No, a fully charged capacitor will eventually discharge due to leakage current and the breakdown of the dielectric material. However, some capacitors, such as electrolytic capacitors, can hold their charge for a longer period of time compared to others.
