1. The problem statement, all variables and given/known data Hi everybody! I know, it's a strange question... Problem is that I'm searching how to translate the german words "stromrichtig" and "spannungsrichtig" ("current correct" and "voltage correct" literally) in English. Any idea? Do they even have a name in English? And if not, how would you describe them with the minimum amount of words? 2. Relevant equations I have attached a picture with the corresponding circuit combinations. 3. The attempt at a solution I have no idea how such word would be translated in English. I've googled it but found nothing reliable. In a paper of Siemens in English, they use the words spannungsrichtig and stromrichtig directly, but since it is a German company I am not sure I can do that as well. Thank you very much in advance for your suggestions. Julien.
