Mean value of alternating voltage

WebMay 22, 2024 · AC, or alternating current, is so named because the current alternates or flips back and forth between two polarities. In other words, the current (and consequently the voltage) is a function of time. This is fundamentally different from direct current that is fixed in polarity and generally constant over time. WebSep 1, 2024 · An X-ray tube has at least one grid electrode arranged between an anode electrode and a cathode electrode. Via a focusing unit, an electron flow from the cathode electrode to the anode electrode is focused in that the focusing unit supplies the grid electrode with a first electric grid potential. The focusing unit is supplied with electrical …
