Re: Larkin in an advertisement...

doesn't go

I do NOT agree that the definition can be extended in the way that JL wants to. It is out of domain (different sense maybe). Gain as normally used in electronics includes the instantaneous case, but not the infinite time case.

number?

But it is not *infinite* gain unless you wait forever. The energy required to change its state is non-zero.

This sort of Larkin "logic" defines a wire as having infinite gain (or as an infinite capacity Write Only Memory - usually on 1st April).

It *is* indeterminate gain since it depends on both how much energy flows through the closed contacts *DIVIDED BY* how much energy it took to change their state in the first place - in your example 45mJ.

It is appropriate for the purposes of determining the current gain to take the time integrals of current flows here rather than the hairy engineers instantaneous value to divide by zero and throw hands in the air declaring it infinite. See Dirac delta and Heaviside functions.

This is another as Jim would call it Larkin absurdity.

Yes. I've used latching relays, Ledex solenoid driven rotary switches and Strowger switches. At the other end of the relay spectrum, I've wired & used holding relays as motor controls, or to make sure that equipment didn't restart after a power failure.

All needed some power to operate, even if only momentary, it was power. Without that input, there will be no output.

Right. How long is "forever", in seconds?

The energy the contacts will switch is unlimited.

Divide.

Those were nice relays. They also sold connectors to make them easy to wire or replace. They used the same switch modules to build large toggle switches.

Not arguing that. An ever increasing energy switched over a finite switching energy is causing the issue here. Unbounded or transfinite are appropriate. Infinite is not.

An exactly why some here rag on him.

I must somewhat agree. It is not good engineering to not account for = both transient and steady state conditions. Declaring either of them meaningless in any situation is not appropriate.

It ain't so much what you don't know, but what you think you know that just ain't so that bites you.

"...it is now accepted usage to refer to transfinite cardinals and ordinals as "infinite". However, the term "transfinite" also remains in use."

"In real analysis, the symbol \infty, called "infinity", denotes an unbounded limit. x \rightarrow \infty means that x grows without bound,.."

[...]

You are of course free to argue that your own definitions are really the correct ones. But it seems a bit daft to be continually trotting out this trivial disagreement over terminology as the time "Larkin Got It Wrong".

Not yet. I still have to hold down a day job. Then the rest of life intrudes. Beats the alternative though.
