relays

I originally gave you an expression which related power gain to the ratio of output power to input power with an eye toward showing you how infinite power gain is impossible to achieve with finite input power. You, however, in an attempt to forestall having to admit that your original statement that latching relays have infinite gain was wrong, chose to pooh-pooh that and, instead, embarked on an error-ridden journey trying to confuse the issue with the seeming intent of, as always, keeping from having to admit making an error. --- >Loser? Business is holding up pretty nicely, so far.

Nope, just a one-time brain fart to which I admitted. You, on the other hand, refuse to admit that latching relays can\'t have infinite gain when you know they can\'t. Why is that? Because you stated, originally, that they could and you don\'t want to have to publicly admit to your error. Especially when it was caught by someone you hold in such high disregard,

Did it get out of joint because of some other mistake you made? ;)

One of the main reasons I moved here was to get away from certain allergens. The scheme worked great for 25 years or so. But I can't move much farther west without drowning, and they won't let me evict the cats. So, medical intervention. I'm sure glad I'm not living 200 years ago, when medicine was useless to fix either noses or hips.

The procedure did involve LEDs and some serious RF power gear.

All the errors, 5 or so, were yours.

Tell me more. What did they ablate? Can you still smell food?

Well, even if that were true, it wouldn\'t make you less responsible for the colossal blunder you made. JF

I used the word "infinite" to mean "unboundedly large and without limit", which is hardly a blunder, and a perfectably reasonable engineering use for the word. Some people do accept this as "infinite." Whether the lifetime of the universe is finite or not is beyond my pay grade.

But at least I got you to advance from your initial simplistic time-invariant equation for the power gain, to one that included time, even if you did use the wrong units. So, in some small way, I have reduced the ignorance of the world a bit.

Our work here is done, kimo-sabe. Hi-Yo Silver, Awayyyyyy.

John

Right. You don't *think* that's right, but it is.

Wrong. The reason is because a latching relay has a far lower energy gain, and it is energy use that drains a battery. This has been explained to you multiple times.

If not for your willful ignorance concerning the difference between power and energy, this would be obvious to you.

Guy Macon

Confusing power per day with power is a clueless newbie error akin to confusing miles (a measure of distance) with miles per hour (a measure of speed). This has been explained to you multiple times.

Guy Macon

Please don't insult real engineers by implying that we do not believe such basic math concepts as unbounded not being the same as infinite. It's just you who has his own non-standard brand of math. The rest of us are using standard math -- you know, like the math in the math textbooks I quoted to you?

Guy Macon

...says the man who started this thread by measuring power in joules...

Guy Macon

I wouldn't either if I were a person who thinks infinite is the same as unbounded despite having someone quote a standard math textbook explaining the difference to him.

Name a single mathematician or philosopher who thinks that there is no difference between infinite and unbounded. Go ahead. Name one.

Please stop insulting engineers by implying that we don't accept the fundamentals of math taught in the textbooks. That's just you.

Guy Macon

Your behavior suggests otherwise.

...says the man who started this thread by defining power gain as joules in and watts out...

(Free clue: the joule is a unit of energy, the watt is a unit of power.)

Guy Macon

...says the man who can't tell power from energy or infinite from unbounded...

For the record, the above assertions concerning John Fields are entirely unsupported by anything that John Fields wrote. They are total fabrication -- a straw man.

Guy Macon

I have no particular dislike for you. You are just wrong and unwilling to admit it, not particularly unlikable.

Guy Macon

Is not.

Nope. Just you.

That's like advancing from your a "simplistic" time-invariant equation of distance (miles) to one that includes time (miles per hour). Miles are not miles per hour. Distance is not speed. Watts are not watt hours. Power is not energy. This has been explained to yoou several times.

Guy Macon

Please define "energy gain", then explain why a latching relay has less of it than a regular relay.

Geez, you're as bad as JF in checking your work.

John

Sure I do, but I have to be wrong first. I'm seldom wrong here, not because I'm a genius, but because I don't make assertions about things I don't understand. That's just being careful.

Neither Guy nor JF have been very careful lately.

Not that it matters; a newsgroup ain't life. One hopes that they *are* careful about stuff that matters.

John

Cite?

Do you agree with JF that power is measured in coulombs?
