While cleaning out the basement I found this device and I have no idea what it is or how much it costs (I want to sell it đŸ˜…) It would be nice if someone could explain it to me

Loading...a) What is the difference between RAM memory and ROM memory? Please also name practical applications for the memory modules mentioned! b) How does the voltage IJ2 differ from Ul in the circuit below? c) Name two bus systems that are frequently used in industrial control technology and give a typical application example for each.
I keep trying to calculate the current through R17 to consider the current source Iq2, but I can't get the result. How do you calculate the current through R17?
I have a question. I want to build a PC that will cost around €1,000 and have selected the following parts: https://amzn.eu/d/0s4AkFb Fan https://amzn.eu/d/hRqTEuq CPU cooler https://amzn.eu/d/bcYMqcx SSD https://amzn.eu/d/geLtFQT Graphics card https://amzn.eu/d/0QyizS3 CPU and motherboard https://amzn.eu/d/0QyizS3 RAM (I don't know much about it, so I'm not sure if it's called RAM) https://amzn.eu/d/0O0Ixyn Case
Or that you can have the picture embroidered with an automatic sewing machine, etc.
Hellooo I urgently need help. I have to explain the function of a warm switch, but not a normal one, but a slightly different one. I'm displaying an image. Please help me!!??
Beautiful good day, I recently purchased a 64GB Intenso USB stick. I'd like to copy my music collection onto the stick and play it on my car stereo. I know from personal experience that my car stereo works best with the FAT32 file system. However, I can only format the stick in exFAT and NTFS…
Scheint ein Labornetzgerät zu sein, evtl. sogar ein Trenntrafo (TrennNetzGerät?) mit einem Ausgang von 12 V/3A.
Da das Gerät vor 1987 gebaut wurde, ist es mit einer Primärspannung von 220 V angegeben. Somit ergibt sich bei der heutigen Netzspannung von 230 V eine Asugangsspannung von 12,55 V.
Damit liegt die Leistung bei knapp 38 W.
I have to correct myself:
The 12.55 V is only present if it is the pure secondary alternating voltage of the transformer.
With a DC voltage, the voltage should still be limited to 12 V by a voltage regulator.
From what it looks like to me, it's a transformer.
It transforms the 220V to 12V with a current of 12A.
It's a laboratory transformer; the red and black sockets can be connected with plugs and used to power things with 12V. So it's also popular in schools or hobby areas.
I think you'll get 20€ for it with luck
It's a 12V 3A DC power supply. I remember it from my youth; it powered mobile CB radios.
A 12V laboratory power supply. This was used, for example, to power and repair car radios in a workshop.
It's hard to say how much it's worth. First, you'd have to know if it still works. If so, then maybe 20 euros. If you can find a collector of old devices, maybe more—but you'd have to find one first.
