Hello,
I have to write a report for a circuit design and note the components in it accordingly. However, the explanation of this component was presented to me in a rather dry manner.
What is the component in the first resistor, the line that runs through the resistor? What is this used for?

Loading...Can I glue the blue and white cables together with hot glue? I can't solder it.
Hello, I disassembled an old radio (Tivoli Audio PAL) that was very dirty and installed the front panel, which houses all the electronics, into a homemade case. (Photo) I used a slightly larger speaker, but it's still not enough for me. A bit more power would be nice. Using an even larger speaker might be…
Good morning, My question is what the H and G stand for in the hardware version of the module, whether it has anything to do with the wiring on the board and why I can't possibly use both versions on one FU? Thank you very much
I accidentally dropped a drop of water on the GPU but the PC was off and I don't know if it will break if I plug it in.
Hello, Where can I add a stopover when planning a route on Google Maps on the web on my computer (Chrome browser)? I can't find it anymore. I've done it many times. Thanks
Hello. I've been wondering lately if there are any delivery services (like Amazon or eBay) that ship from Russia (I'm looking for Soviet computers, so nothing that would generate much profit for the country). I would really appreciate an answer.
It’s called Trimmpotentiometer (short “Trimmer”), i.e. a variable resistance.
If the symbol (at the end of the diagonal line) is a “T” it is a trimmer, whereas this symbol is an arrow, so it is a pot.
There are variable (adjustable) resistors

Good luck!
This is an adjustable resistance, usually a so-called potentiometer (short poti).
They’re used to set something up.
The most famous is a volume control. The rotary knob then weakens the signal so that it becomes quieter. If you turn the button “higher” the signal is weakened less strongly.
Thus, a control voltage can also be set so that a circuit can then be adjusted. For example, you can adjust to a light sensor when it is switched on. For this purpose, the one voltage of the light sensor compares with the voltage of the pot.
Theoretically, it is also possible to adjust the power of a motor or lamp. But there’s a lot of power lost in the pot and that’s getting hot accordingly. In the past, there were gigantic wire potentiometers in the ceramic housing, today this is done electronically and using a small pot that controls the power part with a small, weakly loadable voltage.
Not with a T as a pointer. LG gadus
The T instead of arrow means that the thing is not provided for the user, i.e. is not a rotary knob. Technically but exactly the same.
There are even trimmers (a pot that the user does not want to turn) that with a plug-in button to the pot will be served by the user.
Technically and physically, they are exactly the same. The difference in the circuit diagram only shows whether one can rotate there with the fingers or needs a screwdriver or has to open the housing beforehand.
Thank you

The resistance is linearly adjustable (i.e., for example, with a rotary controller).
Z.b for precise calibrating of the back-connected ampermeter or generally in order to be able to adjust the current.
A control resistor, a potenziometer.
So simply, a resistance decade where you can adjust the resistance yourself?
A resistance decade is something else.
Trimmpotentiometer.
Hello Ivini
This is a trimmer, you can change the resistance
