Basics of Capacitors [Lesson 1] How do capacitors work?
A capacitor does not allow direct current to pass through it, but when the charging and discharging are repeated, a charging current and discharging current repeatedly flow to the capacitor. When this phenomenon is observed from outside the capacitor, it appears as if the current is flowing through the capacitor.-

What is the Working Principle Behind AC Power Circuit?
The AC power circuit has alternating current that flows in it. A current that changes its polarity and magnitude in regular time is known as an alternating current. It can also be defined as a current that changes repeatedly and reverses its direction. The direction of an alternating current is always opposite to that of a direct current (DC).

AC pass through capacitor
In the very instant where the capacitor is connected to the battery, the current flows as if there was no capacitor (a short-circuit). Only after a short while will a bunch of charges have been accumulated at the plate, starting to repel the incoming charges, lowering the current.
Capacitor and capacitance: Working, Properties & Applications
However, it blocks the flow of current as the dielectric of a capacitor is basically an insulator as it is non-conductive. However, when connected to an alternating current circuit, the flow of current appears to pass straight through the capacitor with little to no resistance.

Half Wave Rectifier
A Half-wave rectifier is an electronic device that is used to convert Alternating current (AC) to Direct current (DC). A half-wave rectifier allows either a positive or negative half-cycle of AC to pass and blocks the other half-cycle. Half-wave rectifier selectively allows only one half-cycle of the AC input voltage to pass through, …
19.5: Alternating Currents
The alternating current in appliances can induce an EMF on the case. If grounded, the case voltage is kept near zero, but if the case is not grounded, a shock can occur. Current that is driven by the induced case EMF is called a leakage current, although current does not necessarily pass from the resistor to the case.
Capacitor blocks direct current but easily passes alternating
3 · Hint:Any circuit containing a capacitor, the capacitive reactance offers the resistance to the current flowing through the capacitor. The capacitive reactance is inversely proportional to the frequency of the circuit. As a direct current has zero frequency, the capacitor offers infinite resistance to the current flowing through it.
What is Capacitor and How Does It Work ?
Capacitor Construction. A capacitor is constructed out of two metal plates, separated by an insulating material called dielectric. The plates are conductive and they are usually made of aluminum, tantalum or other metals, while the dielectric can be made out of any kind of insulating material such as paper, glass, ceramic or anything that obstructs the flow of the …
