Please read everything Hello folks! I don't really know much about electronics, so I often experiment and try out my own circuits. I want the diode in this circuit (pictured below) to have two different functions. It should light up when the battery is fully charged and it should light up when the toggle switch…
Hello, I would like to understand how the RS flip-flop shown works. What I know so far is that RS stands for reset and set. Flip-flop means the circuit can flip in either direction. Furthermore, S and R cannot be 1 at the same time, because otherwise it is undefined what happens. If S and…
Hello everyone, The following task is given: (Sorry for the poor quality) We are looking for: mean Rectified value Effective value Peak-to-peak value My problem starts with calculating the amplitude of the triangular signal. Since the signal oscillates around U2, I would say û_triangle would be (-4*U1/pi)+U2. û_Sin here is U1-U2. The peak-to-peak value would…
I have two questions about the following discrete Schmitt trigger. It is designed to go high above 3V and low below 2V. Why doesn't it respond to +2V and +3V, but to -2V and -3V? What do I need to change to make it respond to +2V and +3V? When the Schmitt trigger goes high,…
This Micro USB cable bends so easily, and it doesn't look particularly good either. I want to replace it with USB-C.
Hey, Will a capacitive isolator work to isolate the 230V/50Hz power grid while still allowing my 0-2.5V data signal to pass through? I need an isolator for the connection to my microcontroller. LG Max
Hello everyone, I've built a circuit in every Circuit. Unfortunately, I always get an error message when I try to start it. (Can't find a solution) What could be the reason for this? (The top voltage source has -180°, the middle 0° and the bottom +180°) I have also made the circuit publicly available at:…
Can someone solve the problems for me? Only the first four would work! It's important!
Hello dear community, I have a 400A MIG welder. I noticed that three diodes in the rectifier are defective. They use Siemens E1120 and E1220 anodes and cathodes. Since I can't find them anywhere, and I found an offer for Siemens E1140 and E1240 from an old stock, I'm toying with the idea of installing…
Hello, I wanted to ask what the subthreshold area the triode area the saturation range and where I can identify each area. Plus, how they differ. So, it's more a matter of definition and how I can identify them on the characteristic curve map.
Moin the following task is confusing my head.. I think I'm also a bit confused What's underneath is the solution. But I simply cannot understand this, for example why the resistor R1 is completely omitted for ri, which is in series with R2 if you look from UAB… and then the calculation method with uq……
Hey, When I shift up my MTB it takes a while for the chain to jump. Is this normal? Is downshifting faster than upshifting? Or is it a matter of adjustment? Shimano gearshift. LG
