You need a true RMS meter to read the current. That analog meter is
expecting a sine wave and giving you a faulty reading.

How so? The ONLY effect is to eliminate one half cycle, (and thus halve
the
P-P voltage of course)
Let's hear what you think the new Peak, Average, and RMS voltages are?
Now you losing sight of the wood for the trees. Yes, there's an effect
on the resistance, but only because you're running the bulb above its
rating. If the filament doesn't blow, I wouldn't want to say what the
power will stabilise at, but it will be way way above the rating for the
bulb.

Nope, you still haven't calculated the RMS voltage which is what matters as
far as the filament is concerned.

MrT.



For a 240 volt supply:

Since 240 volts is the RMS value, the mean square is that squared, or
240^2. Since we're throwing away half, the mean square of the result is
240^2 / 2. The RMS of that is then its square root, or 240 / sqrt(2) =
169.7 volts. Put that into a 110 volt lamp, and watch it fail.

Sylvia.

Exactly. Channel master built TV sets for the US market with a
series string of 84 volts and used a 'Dropping diode' in the string.

120 * .707 = 84.84 - the diode drop of approx. .6 volts gives 84.24
as the effective voltage. I repaired a lot of these sets that were made
for use in schools. All had the CRT get weak in under two years from
the pulsing DC filament. By removing it from the series string and
adding a small filament transformer, they got another ten years use from
the sets.

Nope. I'ts already the mean of the instantaneous voltages, squared. You
don't square the RootMeanSquared value to get RMS.
But nice try.

Slight change in calculation needed the lamp is rated at 100w 120v Still
higher than it's taking

Hey now you've spoiled all Sylvia's hand waving fun

You square the root of the mean square to get the mean square.

Well, the jury is still out on that one. Some people believe me to be
a bott, but others think I'm too smart and witty to be a bott, so they
think I'm a real human being.

but they're still wired in series. (unless they are low voltage with a
transformer) they just put something in each bulb that shorts it out if
it sees a high voltage. try removing one of the bulbs.

nine in a row go out. (in all the lights I have)

Yes, think of a number, square it, take the square root, subtract the number
you first thought of, the answer is zero

However your original claim is still wrong.

Who said anything about MALE arseholes ? I didn't assume you were a male, only an idiot.
You seem to be the one obsessed with bodily functions, particularly with males, for some reason.

My suspicions about your bodily urges seems true. Why do you insist
