Kapasitiivsed

Kapasitiivsed refers to something that possesses capacitance. Capacitance is the ability of a system to store an electric charge. It is measured in farads. A capacitor is a device that exhibits capacitance. Capacitors are fundamental components in electronic circuits, used for a variety of applications including filtering, energy storage, and signal coupling.

The capacitance of a system is determined by its physical geometry and the dielectric material between its conductive components. For a simple parallel-plate capacitor, capacitance is directly proportional to the area of the plates and inversely proportional to the distance between them. The presence of a dielectric material with a high permittivity increases the capacitance.

When a voltage is applied across a capacitor, electric charge accumulates on the conductive plates. This stored charge creates an electric field in the dielectric material. The amount of charge stored is directly proportional to the applied voltage and the capacitance. When the voltage source is removed, the capacitor retains its charge, acting as a temporary energy store.

The term "kapasitiivsed" is often used in a more general sense to describe phenomena or behaviors related to capacitance, such as capacitive sensing, where changes in capacitance are used to detect physical presence or proximity. This principle is employed in touchscreens, proximity sensors, and many other modern devices. The behavior of electrical circuits containing capacitors is also described as being capacitive.
