Hello, I'm A09090091. An edit you recently made to P–n junction seemed to be a test and has been removed. If you want more practice editing, the sandbox is the best place to do so. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thank you. A09090091 (talk) 13:18, 26 February 2022 (UTC)

Please stop making test edits to Wikipedia, as you did to P–n junction. It is considered vandalism, which, under Wikipedia policy, can lead to being blocked from editing. If you would like to experiment again, please use the sandbox. Jc3s5h (talk) 14:21, 26 February 2022 (UTC)
