    DonH50 replied to the thread Fuse and Cable Directionality.

    Drift velocity is very, very low, see e.g. https://en.wikipedia.org/wiki/Drift_velocity -- that article lists about 23 um/s for 1 A in a...

    DonH50 reacted to Atmasphere's post in the thread Fuse and Cable Directionality with Like.

    The electromagnetic field is caused by electron flow and vice versa. You can't separate them. The electrons move back and forth in the...

    DonH50 reacted to Atmasphere's post in the thread Fuse and Cable Directionality with Like.

    Some wire responds to being moved rather than anything to do with directionality (which seems to have more to do with the dielectrics...

    I can't speak to "sonic gain" and such, but the rest of it is (ahem) sound advice. The safety ground is also important. One thing nobody...

    DonH50 reacted to Kingrex's post in the thread Fuse and Cable Directionality with Like.

    In 120 volt circuits, I find the entire magic with grounding is attention to the branch circuit neutrals and their relation to the...

    DonH50 replied to the thread Fuse and Cable Directionality.

    Since you were conflating "wall" and "speaker" wires for directions I was confused. So you are saying that, for any two wires (planes...

    DonH50 replied to the thread Fuse and Cable Directionality.

    The AC wires for wall power coming into an amplifier are decoupled from the speakers by the power supply. There is virtually no relation...
