Glühbirne RGB Umbau mit Filter?
ByLAUCH375
Hallo, ich habe noch einige 60w Glühbirnen und würde diese gerne auf RGB umbauen. Dazu würde ich gerne einfach einzelne mit Farben anmahlen (Rot, Grün, Blau) oder einen Filter vor die Birnen setzen. Kann man Glühbirnen einfach anmahlen oder gibt es dabei Probleme wie Überhitzung?
Kontaktanschlüsse bezeichnen?
ByMetsoHD8
Kann mir hierbei jemand helfen?
Ist die magnetische Flussdichte des Magnetfelds, was durch eine stromdurchflossene Spule erzeugt wird, abhängig von der angelegten Spannung an der Spule?
Es gibt ja diese Formel für die magnetische Flussdichte innerhalb einer stromdurchflossenen Spule. Ist B anhängig von U und falls ja, wie lautet die Formel?
Dopplereffekt Feldlinien?
Gibt es eine Art Dopplereffekt bei Magnetfeldern, sodass sie bei Bewegung auf einer Seite zusammengepresst und damit stärker sind als auf der anderen. Klingt mega dumm, ich weiß, ist aber mein einziger Ansatz, Aufgabe 3 mit einer magnetischen Abstoßung zu lösen… Danke schonmal für die Antworten (hoffentlich)
Durchlauferhitzer offene oder geschlossene Anlage?

Ist ein Durchlauferhitzer eine offene oder geschlossene Anlage? Und warum?
We cannot know what is in principle and not only applies to Tesla. You can also ask this question retrospectively from that time, according to the motto: “Had people had things before Tesla even before Tesla arrived?”
Inventions in the world of electrical engineering are always based on other inventions or findings. For example, a radio was not invented by a person. Rather, there are many small findings that have been summarized with time. Each inventor or engineer then contributes to this at that time, creating increasingly complex structures.
Tesla was a brilliant engineer and contrary to the supremeness of some others, he should be given sufficient respect for his contributions. He was particularly impressed by his reflections, improvements, additions and innovations, and has no more than 200 patents. He is therefore by no means comparable to conventional engineers or physicists. Not every one of these gets to honor a unit.
I do not want to make Tesla small, after all he has made some important technical inventions, and without a doubt he was technically very talented. But he is highly overestimated: he has not only contributed anything material to the physics of my knowledge, but has also been completely overrated several times in it (“free energy”).
The overestimation of Tesla is probably due to its esoteric considerations, which are becoming increasingly stronger towards its end of life, which are very well received in circles that rely on “alternative facts” and reject the teaching opinion.
I would say Tesla was a good engineer – more but not. His contribution to physics is not only ending, but not present.
I think that basic findings have only led Tesla to make his inventions. Once the most important findings of nature are recognized, it is only a matter of time until someone finds a way to make this knowledge useful. This is the essential task of technology.
The findings of Maxwell are much more important for electrical engineering. Without the 4 Maxwell equations or the findings behind it, today’s electrical engineering is not possible. With only 4 equations, Maxwell provided the basis for important laws such as the Induction Act.
His discoveries would have brought someone else back. So today it would look similar, maybe with a few years delay
The development would certainly have been delayed and could have been partly different.
Some think Tesla is overvalued. Others were more important.
I don’t see that. Tesla was definitely one of the most ingenious engineers ever on earth. Those who see him overrated have not dealt with his achievements in many ways.
Tesla has not invented the three-phase system from scratch, the pre-developments have been otherwise. The genius of Tesla was to recognize the advantages and develop a compact system. Without him, everything would have been slower.
Thomas Alva Edison also gave it, that was the time of inventions.

Yeah, then someone else would have discovered that invented.
When?
Hopefully you don’t want to say that the question of the “wan” is not quite stupid. Or is this going slowly into a troll post?
Without him, or someone else at his place, the alternating current develops and wirelessly imagined, our world looked very different.
You work in web development.
Can you get there without a Bachelor in IT?
I studied mechanical engineering.
Companies always want IT studies.
For frontend you do not need a diploma as long as you can demonstrate experience and a good portfolio.
But I’m self-confident and that’s different from a company. And most of those I know in the field have come to their job in a company.
This is a more than daring claim.
Because employers, just like all other people, prefer the acquaintance. I don’t want to say that you don’t get a good job about applications, but a network in itself is very important.
Why are relationships so important? Why not by application?
Tesla’s share of technological development is greatly overestimated.
Was he smart?
