Prądowe, a nie napięciowe źródła energii

B051Another video in the series showcasing the fundamentals of wired electronics ("wireless electronics" is much more difficult). In this video, I discuss extremely important, yet unfortunately poorly understood, current sources. I demonstrate the operation of a near-ideal voltage source and a decent current source with surprising parameters. This video is a supplement to an article from the December issue of my magazine (ZE 12/2025). A shortened, overview version is here: https://piotr-gorecki.pl/wp-content/u...
