kapatsitiivseteks

Kapatsitiivseteks is a Finnish term that translates to "capacitive" in English. It refers to anything that has the property of capacitance, which is the ability of a system to store an electric charge. This storage is typically achieved through the presence of one or more pairs of electrically conductive surfaces separated by a non-conductive dielectric material.

The fundamental unit of capacitance is the farad (F), named after Michael Faraday. One farad represents a large amount of capacitance. More commonly, capacitance is measured in microfarads (µF), nanofarads (nF), or picofarads (pF). The amount of capacitance depends on the geometry of the conductive surfaces and the dielectric properties of the material between them.

Capacitive effects are fundamental to the operation of many electronic components and devices. Capacitors are the most direct application, used extensively in electronic circuits for filtering, energy storage, timing, and signal coupling. Beyond discrete components, capacitive principles are utilized in touch screens, where the presence of a finger alters the capacitance of the screen, allowing for interaction. Sensors that measure displacement, pressure, or liquid levels can also employ capacitive sensing by monitoring changes in capacitance. In electrical power systems, parasitic capacitance can also be a significant factor, influencing signal integrity and power loss. The term "kapatsitiivseteks" therefore encompasses a broad range of phenomena and applications related to the storage of electrical energy in an electric field.
