Hello, I'm Bruce1ee. I wanted to let you know that one or more of your recent contributions to Electrical impedance have been undone because they appeared to be promotional. Advertising and using Wikipedia as a "soapbox" are against Wikipedia policy and not permitted; Wikipedia articles should be written objectively, using independent sources, and from a neutral perspective. Take a look at the welcome page to learn more about Wikipedia. Thank you. —Bruce1eetalk 06:57, 25 May 2020 (UTC)

Please do not add promotional material to Wikipedia, as you did to Operating empty weight. While objective prose about beliefs, organisations, people, products or services is acceptable, Wikipedia is not a vehicle for soapboxing, advertising or promotion. Thank you. —Bruce1eetalk 07:16, 25 May 2020 (UTC)
