    Checkiing to buy a transformer, I see most of them don't publish the output
    amps but do give a stat 'VA'. Is this just wattage?. .. .chas

    ** Generally no.

    VA and watts are the same only if the load is resistive, like incandescent
    lamps.

    By using VA , the makers are letting you know that a transformer can deliver
    a certain load current in RMS amps and no more.

    It is possible for the watts actually delivered to the load to be zero, if
    the load is a pure capacitance or inductance, and the tranny is still
    operating at its max safe current.

    Phil, I think you better read it closer yourself, Tim has outwitted you
    with that statement.
    I know you guys down under have a totally different understanding
    mechanism but come on now, is it really that bad?

    ** That is a REALLY STUPID and fowl remark.

    There is NO medication on earth that cures what YOU have - asshole !!

    FFS : READ WHAT YOU WROTE !!!!!!!!!!!!!!!!!!!!!!!!!!!

    What does it fucking say ???????

    -------------------------------------------------

    Here it is again - you fucking, posturing TWAT

    The transformer doesn't care what power is traveling through it.

    --------------------------------------------------

    ** Still got no idea how STUPID it is to say that ???

    Transformers can pass infinite amounts of power can they ?????


    FFS, dickwad:

    1. Learn to write clear English.

    2. Learn to READ what others are REALLY asking and saying.

    3. Learn to fucking READ what you write yourself for the MOST OBVIOUS
    meaning.


    Now - **** off usenet entirely until you can do all three.

    I expect to see ya back not earlier than next century.

    Shithead.

  9. Geesh Phil, I guess you can take Tim's line out of context and take it
    to mean the above. But I had no trouble understanding what Tim was
    saying. (And I'm far from a transformer expert.)

  11. holy smokes. I want to know more about the "fowl remark" you're talking
    about, and how it applies to your steps 1, 2 and 3.

    ** Why not address the issue instead of trolling ?

    Or is the latter ALL you are capable of ?
