DC current does pass through a capacitor. If you connect an ideal capacitor to an ideal current source, the current will flow through the capacitor forever (click for simulation): But note that the voltage across this ideal capacitor is continually increasing. Obviously this is not possible in the real world, as something will break down and/or ...
When we connect a capacitor across an AC supply source, it starts charge and discharge continuously due to continuous change in the supply voltage. This is due to changes in AC voltage i.e. AC is positive in the initial cycle for “t = 1” and negative in the second cycle “t = 2” as shown in fig below.
In essence, a capacitor stores electric charge and releases it when needed. When a voltage is applied to a capacitor, the electrons in one plate accumulate and repel electrons in the other plate, which causes a transfer of charge between the two plates. This creates an electric field in the capacitor and charges it up.
As a result, the capacitor is charged, which means that there is flow of charge through the source circuit . If a time-varying voltage is applied across the leads of the capacitor, the source experiences an ongoing current due to the charging and discharging cycles of the capacitor.
If a time-varying voltage is applied across the leads of the capacitor, the source experiences an ongoing current due to the charging and discharging cycles of the capacitor. However, no current actually flows through the dielectric itself.
In AC circuits, capacitors allow current to flow through them by continually charging and discharging in response to the changing voltage. This interaction with AC is a crucial reason why capacitors are used in various AC applications like signal filtering and energy storage. 3. The Role of a Capacitor in Circuits
However, a capacitor does not conduct all forms of AC current in the same way: its capacitive reactance is inversely proportional to the frequency of the AC current. Capacitive reactance (Xc) is expressed as 1 / (2πfC), where f is the AC frequency and C is the capacitance of the capacitor.

Because the electrodes of a capacitor are separated by the dielectric, a current will flow momentarily in the conductor during the charging process, but the current will not actually pass through the dielectric inside the capacitor. In other words, the capacitor blocks the flow of direct current (DC). By contrast, when an alternating current ...
Yes, current does flow through a capacitor, but not in the same sense as it flows through a conductor, as a capacitor is designed to store and release electric charge.

Capacitors can pass alternating current (AC) because the voltage across them changes continuously. As AC voltage fluctuates, the capacitor charges and discharges rapidly, allowing current to flow in a back-and-forth motion.

A capacitor (historically known as a "condenser") is a device that stores energy in an electric field, by accumulating an internal imbalance of electric charge. It is made from two conductors separated by a dielectric (insulator). Using the same analogy of water flowing through a pipe, a capacitor can be thought of as a tank, in which the charge is often thought of as a …
