Hello, I'm Guðsþegn. I wanted to let you know that I undid one or more of your recent contributions to Kirchhoff's circuit laws because it didn't appear constructive. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Guðsþegn (talk) 21:18, 29 January 2013 (UTC)
