Hello, I'm EN-Jungwon. An edit you recently made to Maximum power transfer theorem 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. EN-Jungwon (talk) 05:55, 20 November 2020 (UTC)
