Re: Hey do you know your car's alternator only outputs 7-10% while it'srunning?

That is NOT what he stated. He stated that they were run at 1:1 of the
engine speed, and that is what I refuted. You need to learn how to read.



I believe that you should **** off until you learn how to read. No I
am not talking about only getting PART of what you read either.

I was responding to YOU, not him.

Since when has a woman ever taken any notice of noises coming from the
engine?

Good point, but the obvious answer is:

"Whenever the noise has no bearing on the operation of anything..."

I know my script.

You're an idiot. The engines of the 50s and 60s redlined above 5000
rpm.

3600 rpm was the model T years, you ditz.

1962 buick v6- max hp rated at 4600 rpm
1949 buick straight 8 - max hp rated at 3600 rpm
1958 buick 364 v8 - max hp rated at 4400 rpm
1957 caddy365 v8 max hp rated at 4400 rpm
1953 chevy max hp at 3600 rpm
1958 6 cyl chevy max hp rated at 4200 rpm
1958 chevy v8 - max hp rated at 4600 rpm
1949 chrysler max hp rated at 3600 rpm for the 6, 3200 for the 8.1954
chrysler hemi - 331 cu in - max hp at 4400 rpm
1953 forf flathead 0 max hp rated at 3800 rpm.
1955 ford "Y" block max hp rated at 4400 rpm
1953 hudson max hp at 4000 rpm
1957 rambler 6, max hp at 4200 rpm
1955 olds rocket v8 - max hp at 4000 rpm
1954 pontiac six, max hp at 3800
1954 pontiac 8, max ph at 3800 rpm

worked on these babies - I know how fast they ran. NOT MANY engines
of the 50s would even rev to 5000 without losing parts. Many stock
engines of the 60s and 70s could not rev over 5000 rpm Most redlined
WELL UNDER 5000.

Even the mighty Chevy 396, in stock form in 1966 was not happy much
over 4200 rpm. With aftermarket parts, or the L34 factory hotrod
version, they would hang together for a while at 5000 RPM.

A slant six 225 Dodge would not hit 5000 RPM stock - the little 170
could wind to 5500 with its 1 inch shorter stroke.

The 6 amp motor means it draws 6 amps from the mains. It does not mean
ANYTHING as far as how much power it produces, other than that it
cannot produce more than 690 watts at 115 volts

You're an idiot. First off, there are ZERO 115 volt circuits here.

Secondly, everything that runs on standard AC that relates to raw power
is declared in Amps.

Look at vacuum cleaners, and the hand drill.

Anything that competes with other makers that runs on a motor, competes
with each other over how fast or how strong or how well it can do the
job.

A dremel tool talks about top rotational speed as that is more important
than shaft torque.

Drills and vacuum cleaners refer to the amperage of the motor.

So, YES it DOES mean EVERYTHING about how much power it has in a world
where the source voltage is known.

You are both wrong.
With AC, Volts x Amps only gives the power with a resistive (heating)
load.
If you have an inductive load this is no longer true. (ie a motor.)
If it was a pure inductor, you could draw as many amps as you liked
and no power would be consumed.
Pure inductors only exist in theory BTW.
If you connect a capacitor across the mains, it will draw current but
no power will be consumed (virtually).
Pure capacitors (as near as dammit) exist.

The pair of you study this:
http://en.wikipedia.org/wiki/Power_factor

I don't know where you Yanks get educated. God help America!

First of all, I'm no yank.
Second of all, That's what I was aluding to when I said the amperage
rating REALLY doesn't tell you how much power a device puts out. It is
an indicator, but does not take into account things like efficiency,
power factor, and a whole lot of other things that most people don't
even think about, much less understand. It ONLY tells how much current
is being drwn

As for no 115 volt circuits, OK, say 330 and double the wattage
(1380), or 240 and it is 1440 watts.

All the more reason AMPERAGE is not a good indicator of power output -
it doesn't tell you what voltage it is based on.

Wattage does. And wattage takes into account power factor, inductive
and capacitive reactance, etc. - making it a much more reliable
indicator of power output - but still does not address the efficiency.

Horsepower (or foot lbs torque at rpm, or newton-meters torque at RPM,
etc) does.

I know exactly what it means. I also know that corded tools in the USA are
rated in amps these days. I even provided a random link to demonstrate that
FACT. So whether you or richardson claim it is never done I have
demonstrated that it IS done. An apology would be asking too much so just
accept that you have been successfully refuted and let it go at that.

Yes, tools are advertised and rated in North AAMerica by their
Amperage. This is, however, NOT power. It is advertizing gobbledegook.
It is "dumbed down" specifications.

They went to advertizing amperage on vacuum cleaners after they were
called to the carpet for using inflated "air horsepower" ratings for
years. You could buy a "4 hp" vacuum cleaner that drew 10 amps on a
115 volt circuit. By any accepted way of calculating, that machine
could not produce more than roughly 1.4 HP.

Same thing with air compressors.
Because of litigation expense, and having to proove their device put
out the power they advertised, they went to rating the machinery by
amperage drawn at full load - which could be measured, was more
difficult to "fudge" and easier to prove in a court of law.

Car stereo audio power output declarations had similar problems.

You're a goddamned retard, and I OWNED generators and I knew at ten
years old why they were changed out to alternators by the industry
because I worked on cars back then. I knew what Chilton's was before your
little pussy ass was even born, boy.

Delco factories were right up the road, and Detroit was a little
farther.

You couldn't teach a fucking dog a pavlovian response. That is truly
sad.

Plonk? It takes a true retard to announce his filter edit sessions.
You are one such retard.

Gee, a new alias for you because you can't stand being plonked? Pity

Have you returned to constant current power distribution with 6 A
circuits ?

Arc lamps in the 1880's were specified by the number of amperes
(typically 6 A for street lighting). All lamps were series connected
and you could operate 20-25 of these in series from a 6 A DC generator
producing a 1000-1500 V DC loaded voltage. Thus, the voltage drop
across each arc lamp was about 55 V on average.

That's interesting. How would you strike an arc on series wired arc
lamps? Seems near impossible...?

One at a time while the others are shorted.

When powered down, the electrodes touch each other.

When power is applied to the chain, the nominal loop current will flow
through the electromagnet and electrodes. The magnets starts pulling
the electrodes apart and when the electrodes in one lamp are separated
from each other, the loop is broken and the full generator open
circuit voltage (apparently 1-2 kV) is across the electrodes.
Apparently the inductance in the electromagnets also help create large
voltages peaks across the electrode gap, when the loop current is
interrupted, further helping in striking the arc.

When the arc and electrodes reaches normal operational temperatures,
the voltage drop across the arc is reduced, thus more voltage is
available across the other lamps to start them. I have no idea how
long it takes, before a string of 20 arc lamps will achieve a stable
condition.

What? That bologna is a winner? Then you don't know much about Wattage and AMP.

This is what is wrong with your winner:



600watt can be any form of voltage, it is a combined Voltage and AMP together to form a power of 600watt, you can't say it's fixed to 115V. 12VDC can light up a 600watt light bulb too.

Yup, now you just confirm that you American are jerks!

Thanks jerk. I'm not an American, and don't post from an Amewrican
address like you apparently do.
Go take a flying leap.
