kapazitäre

The term "kapazitäre" is a German adjective that translates to "capacitive" in English. It refers to properties or phenomena related to capacitance, which is the ability of a system to store electric charge. Capacitance is a fundamental concept in electrical engineering and physics.

A capacitive element, such as a capacitor, stores electrical energy in an electric field. When a voltage is applied across a capacitor, electric charges of opposite signs accumulate on its conductive plates. The amount of charge stored is directly proportional to the applied voltage, and the constant of proportionality is the capacitance. This capacitance is determined by the physical characteristics of the capacitor, including the area of its plates, the distance between them, and the dielectric material separating them.

In circuit analysis, capacitive behavior is characterized by the fact that current can flow through a capacitor only when its voltage is changing. The relationship between current (I), capacitance (C), and the rate of change of voltage (dV/dt) is given by the equation I = C * (dV/dt). This means that a capacitor opposes changes in voltage, acting as a sort of electrical inertia.

Capacitive effects are important in a wide range of applications, from simple electronic filters and energy storage devices to more complex systems like touchscreens and radio frequency circuits. Understanding capacitive principles is crucial for designing and troubleshooting electrical and electronic systems. The term "kapazitäre" is thus used to describe anything that exhibits or utilizes these capacitance-related characteristics.
