Synchronization Hello I m Vertium I noticed that you recently removed some content from Synchronization alternating current without explaining why In the future it would be helpful to others if you described your changes to Wikipedia with an accurate edit summary If this was a mistake don t worry I restored the removed content If you would like to experiment please use the sandbox If you think I made a mistake or if you have any questions you can leave me a message on my talk page Thanks Vertium When all is said and done Hi The information appeared duplicated on my browser after multiple refreshes but the current page looks okay I guess it was a technical issue Sorry for the inconvenience I don t edit wiki often so please let me know if I m in error Thank you
