Hello, I'm Donner60. I noticed that you recently removed some content from Alternating current with this edit, without explaining why. In the future, it would be helpful to others if you described your changes to Wikipedia with an edit summary. If this was a mistake, don't worry, the removed content has been restored. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks. Donner60 (talk) 17:58, 2 June 2015 (UTC)
