John: This article ( https://wodewangzhishime.blogspot.com/2022/03/httpswodewangzhishime_7.html ) mention about the direction of current flow of RJ45. Me: OK. John: Now, we look at the 3rd picture. The direction of current flow of the secondary coil must be opposite to the direction of the current flow of the primary coil. Me: Correct. If we don't do that, the current flow of the primary coil will stop. . John: Now, I change the story a little. Me: OK. . John: The direction of the current flow of the secondary is occassionally opposite to the direction of the current flow of the primary coil. Me: Occassionally? John: Yes,. Me: Then, a carrier wave will be formed. John: Now, we look at the 2nd picture. Me: OK. . If the direction of the current flow the Port B is occassionally same as the direction of the curr...
