Katodovými

Katodovými is a term that appears to be a grammatical form of a Czech word, likely "katoda." A katoda, or cathode, is the negatively charged electrode in an electrical device. In electrochemistry, it is the electrode where reduction occurs, meaning it gains electrons. In vacuum tubes, such as cathode ray tubes, the cathode is heated to emit electrons. These electrons are then accelerated and controlled to interact with a screen or other components. The term "katodovými" would likely be used in a plural or oblique case, indicating "by cathodes," "with cathodes," or referring to something belonging to or related to cathodes in a more complex grammatical construction. Without further context, it is difficult to provide a more specific explanation of its usage. However, its root clearly points to the fundamental concept of a cathode in electrical and physical contexts.
