Can someone do a better job of explaining the 3V output shown?
Am I correct in assuming that if I was drawing less than 1 Amp I would then get my full 9V at the output?
外围体育投注At more than 1 Amp does the electricity start to flow backwards in some way?
Hi r/AskElectronics外围体育投注! This is the tube bulb fitting at my Grans house, the bulb recently blew and she had to remove it, which she did by pulling on either side. Now, we can’t get the new one in. It looks like the inner black ring should rotate 90° to align with the slot at the bottom, but we can’t work out how to do this. Any idea on what we can do? Thanks!
