This has been discussed to death. You can find many threads discussing this. https://www.eevblog.com/forum/beginners/why-not-change-conventional-current-to-electron-current/ |
| SparkyFX:
The technical definition of direction was formed before the physical direction was known, therefore symbols are oriented after the technical direction. Technically holes can "move" by electrons filling the void. |

Think of holes as positive charge carriers. The lack of an electron is just as powerful a concept as the electron being present. Sent from my iPhone using Tapatalk |

It was Franklin's fault: https://en.wikipedia.org/wiki/Electric_charge#History He also posited that when matter contained too little of the fluid it was negatively charged, and when it had an excess it was positively charged. For a reason that was not recorded, he identified the term positive with vitreous electricity and negative with resinous electricity. |
