  1. Does anyone have a guess as to what kind of power a fan like this draws, on
    low speed?

    The product manual is on Amazon and says 120 volts, 0.52 amp (i.e., about 63

    Presumably, that is for high speed. As a rough guess, the lowest speed
    might be 1/4 of that.

  4. I am very ignorant about electricity. Volts x Amps = Watts? Very good to

    What bloody fan ?

    The one up your ass ?

    That's 63 VA


    Jeez, talk about beginner's mistakes.

    Except it's wrong for AC

    V x A = VA

  8. Were you breast-fed as a child?

  9. Yes, by his dad. Isn't it obvious? He bounces around all the
    electronics newsgroups while doing his best to piss everyone off, and he
    hates America with both neurons.

    Service to my country? Been there, Done that, and I've got my DD214 to
    prove it.

    For AC this is only true if the volts and amps are in phase; otherwise the
    watts can be somewhat less than the volt-amps.

    Not a mistake, a simplifying assumption. We don't know the phase
    relationship between the voltage and the current. The power is 63 W or
    less, we don't know how much less. Nor do we know why he wants to know the
    power, or whether he's actually concerned about power limits or current

    At a unity power factor yes, but as the power factor drops (reactive loads
    like motors and such) the wattage will be lower than volts x amps would give

    I'd plug in the one I've got here and check, except it's in the "junk
    box," having died long ago -- in fact, not that long after I bought it,
    as I recall.
