    Yeah but Electromagnetics is the DEEP magic behind electronics.

    You could, if you wanted, use quantum mechanics and electromagnetic field theory to do circuit design. But unless you’re building quantum computers or doing simple circuit analysis and wanted a real challenge applying Kirchhoff’s Laws, there’s no need.

    So you can use the simplified electronics model where the current (and therefore primary charge carriers) is positive.

    Using Reddit on web is no good for me since I can’t look at it during work and at home I’d rather watch YouTube.

    Baconreader was the only 3rd party app I liked and now Connect for Lemmy is a good replacement for it to check occasionally.

    I also like that there’s less new posts compared with Reddit so I now spend more time reading than I did before.

    Also the community here feels much more welcoming.

    Up Lemmy!
