Capacitors are one of the most widely used electronic components in electrical circuits and have various applications such as isolated direct traffic, coupling, bypass, filtering, tuning circuit, energy conversion, and control. In DC circuits, capacitors act as circuit breaks. Capacitors are widely used in the fields of... (rest of the passage remains unchanged)
Connecting a capacitor to a battery starts charging the capacitor. Electrons flow from the negative terminal of the battery to one plate of the capacitor and from the other plate to the positive terminal of the battery. This process continues until the voltage across the capacitor equals the voltage of the battery.
The capacitor maintains a potential difference across its plates equal to the voltage of the power source. This potential difference is accessible when the capacitor is connected to another circuit element.
When a capacitor is connected to a power source, electrons accumulate at one of the conductors (the negative plate), while electrons are removed from the other conductor (the positive plate). This creates a potential difference (voltage) across the plates and establishes an electric field in the dielectric material between them.
The capacitor acts as a reactive component that impedes the flow of AC to a degree that depends on the frequency of the AC signal. The capacitor charges and discharges cyclically, resulting in an AC current flowing through it. The concept of the capacitor dates back to the 18th century.
A filter capacitor removes the signal in a certain frequency band from the total signal in circuits. For example, in a tuning circuit, the capacitor used is called a decoupling capacitor, which is used in the DC voltage supply circuit of a multistage amplifier.

The size of that small resistor is usually given on the data sheet for the family of capacitors you''re using. Often, though, you don''t care what that value is, because you''re going to use your own resistor, which should be a few orders of magnitude bigger than the "effective series resistance" associated with the capacitor, and it''s OK to ...

capacitor
Capacitors that go from VCC, Vref, or similar input to GND are called bypass or decoupling capacitors. The idea is that they help to reduce noise from power supplies or voltage references. Noise can often look like rapid transients and decoupling capacitors will help to shunt, or resist, these sudden changes in voltage.
