benefits from having even a few geniuses.
Look at China
Now is-a-hell hits Jemen.. US weapon factories are having a party,
you pay more taxes..
Bad system.
As your enemies get more powerful and more unite, you are a sitting duck.
Just a big war industry making war to sell at taxpayer's cost
making losses, a deficit the greatest on earth and in history.
Should any sane person ADMIRE that disaster?
Half senile president and an ego tripper criminal as aspiring precedent.

example are both 1k so it's half the supply rail. But you knew that
anyway.
The answers you gave show that you know your subject. Unfortunately,
as we know from what John's stated here before, the graduates he
interviews have no idea what the fuck they're doing. The Chinese are
going to kick our arses if they aren't already.
Oh - and carbon resistors are noisy. And I don't think you mentioned
the source resistance of the supply. We could go on. And on. And
on.... But that's not what John asked for. He only wanted a first
approximation which would be 5 Volts. But that's too much for today's
grads, it seems. :(
Sure, but I find it hard to believe,
we had a lab and were required to do measurements etc.. in my school days.
Not only electronics, some mechanics too.
But indeed there is nothing like practical experience, in my school
it was known that only hobbyists would psss the exams...
Electronics is a huge field, on top of that now comes programming.. oh and now AI..
And ever higher frequencies... ever more software (like peeseebee software for example)
protocols, what not... standarss...
And in spite of all that : US could do a moon return in the sixties, July 1969
now they are stuck and need to be saved from the ISS..

applicants. He shows them a diagram of two 1k resistors in series with
10V across them and asks them what the voltage where they join is. If
they freak out, burst into tears or defenestrate themselves, he knows
not to hire them. :-)
Yes I did read that posting
Its hard, lemme see, e=m.c^12 likely does not help.
to make it easier for me I use volts, so if 3k3 + 4k7 in series gives 8 volts
then we know 3k3 gives 3.3 V across it and 4k7 4.7 volts across it
Best is to use trimpots to get the right value, no math needed...
And of course you need to bring the (multi?)meter impedance into play, especially for high
value resistors and moving coil meters from old boat anchors for example.
And there are LDRs and NTCs and PTCs, so we need to know all that
and the temperature and light intensity...
for the NTCs and PTCs we also need to know the current and time since switch on...
So no wonder if they defenestrate themselves.
An other issue maybe length contraction due to near light speed that may affect both measurement equipment and resistors.
And reading those colored bands around some resistors to get the value.
and wirewound, carbon composite, metal,
And then J.L. did not specify if it was DeeSee or AH!See
Imagine 2 1k resistors, one wire-wound, the other metal flim,
The wire-wound would work as inductor for RF, so would some small metal ones with some turns on it..
And then there are tolerances, simple maybe for 2 resistors from the same batch
but tolerances, sometimes a silver or gold band will give a clue
will change the outcome.
So as the saying goes: "Resistance is futile, you will be assimilated"
Opps, composite carbon reisors maye aso be sensitve to moisture? And maybe pressue?
Those would often go high in teefee sets...

Jan, you're massively over-complicating this! :-) The resistors in myOn a sunny day (Thu, 26 Sep 2024 16:21:31 -0700) it happened john larkin
I have had to work with newcomers, some knew nothing
But then when I started... in my first job designing a.o. mil stuff
I had to figure it all out for myself the same day the requests got on the table.
One old guy, who had some experience with electronics but had a lot with high power stuff..
and a manager to rule us, was the environment, and a big factory floor building the things we came up with, and
a test room (HV stuff 100 kV etc megawatt stuff.. and a little corner and oscilloscope for me to test what I came up with,
build proto circuits.
Later when starting in broadcasting we got 6 month in the school benches in their own studio, while getting payed,
and exams after that, everything from audio, video, satellite, management, politics (who can do what, red phones sort of
thing), the works.
As that (video, audio etc) was my real interest, I found it relaxing and fun.
Then when you are put in charge of a real event, I remember the first day I ran alone in a head control room
I had to call my boss back from his dinner in some restaurant.. could not find the cables we had to swap
to sync some remote location,
turned out those were hidden under the floor boards ..
Did not they tell you that?
(Must have missed that :-) ).
It all depends,.
Do you give the poor new guy training? ANY kind of training?
He doesn't have to. John has this screening technique he uses for jobhttps://finance.yahoo.com/news/bosses-firing-gen-z-grads-111719818.html

Being reflexively anti-American is no substitute for thinking. I still
think that the USA is the best place to design electronics.
