Kapasitivinen

Kapasitivinen is a Finnish adjective meaning capacitive. It describes a property or phenomenon related to capacitance. Capacitance itself is a measure of how much electric charge can be stored on a conductor for a given electric potential. A device designed to store electric charge is called a capacitor.

In electrical engineering, "kapasitivinen" can refer to several things. For instance, a "kapasitivinen anturi" is a capacitive sensor, which works by measuring changes in capacitance. These sensors are often used for proximity detection, touch sensing, or measuring levels of non-conductive materials. The principle behind these sensors is that the presence of an object near or in contact with the sensor changes its capacitance.

A "kapasitivinen kytkin" is a capacitive switch, commonly found in modern electronics like smartphones and touchscreens. When a conductive object, such as a finger, approaches or touches the switch, it alters the capacitance between electrodes, triggering a response. This technology has largely replaced mechanical buttons in many devices due to its durability and sleek design.

The term "kapasitivinen" can also appear in discussions about electrical circuits and power systems. For example, "kapasitivinen kuorma" refers to a capacitive load, which draws leading reactive power from the source. Understanding capacitive properties is crucial for designing efficient and stable electrical systems, and for troubleshooting issues related to power factor and signal integrity.
