Someone I know had recently purchased a piece of computer equipment (a
flatbed scanner, I think) and discovered that it didn't work when he
plugged it into his AC power strip. To make a long story short, he
discovered that the power strip had a "reversed-polarity" (which I
assume meant that the left-hand prong of the power strip plug was
connected to the right-hand slot in the power strip's outlets instead
of the left-hand slot, and vice versa).
Back in the old days of DC, polarity obviously made a difference.
But how would reversed-polarity make a diference in Alternating
Current?
Furthermore, if he used a power strip, I assume he had other computer
components plugged into the same power strip (such as a printer and
monitor) which apparently still worked despite the reversed-polarity.
So how come reversed-polarity affects some AC components and not
others?
