Electrical engineering bridge transverse voltage?
Can someone help me with the following problem? I don't quite understand what exactly the problem requires or how to solve 1.3.

Bicycle?
Hello everyone, what could be the reason if you can switch from easy to medium and also from hard to medium but not from medium to hard. Towards the end of my 2-hour tour, I noticed that the chain no longer jumps onto the heavy sprocket. What can you do? Or what would you do…
Battery weird?
I found a battery that looked like a big round ball. Can anyone tell me what it is?
Stopwatch with up to 1000 hours?
Hello, I would like to time myself while I work to see how many hours it adds up to. Do you know of a stopwatch where I can time the time continuously up to 1000 hours? So far, I've only seen it up to 12 or 24 hours. Thanks in advance.
Power outage on only one floor?
ByDodnnodm
Hello I was on the second floor of my grandparents' house when I suddenly heard a clicking noise, and then the lights went out on the entire floor. Since I still had Wi-Fi, I went downstairs. When I got downstairs, I saw that the power was still going. Is it possible that the power was…
How does this relay work?
Hello community, I used to dabble in electronics a bit (although I'm far from a pro). Now I'm planning to delve deeper into it for a project, so I've dug out all my old stuff from the closet. I found several 5V relays that really raise questions about their function. The relays are all 5-pin,…
Good laser engravers?
Good bye, I'm hoping for recommendations for large, enclosed laser engravers/cutters (approx. A3 or larger) as there are many models and manufacturers, which is why it's difficult for me to decide on a device. I actually want to laser on all materials(²), but I attach great importance to very good quality images on wood and…
The bridge voltage is therefore (as described in 1.2) the difference between the two center voltages Um (against ground) in the middle of the two voltage dividers.
These two center voltages Um1 and Um2 (voltage divider) can be written up as a function of the respective two resistors and then the difference Ud=Um1-Um2 can be formed. That’s all!
What do you mean by “as a function of the respective two resistors”.
Should I just write Um1 = R1 *I and Um2 = R2 *I and then (R1 *I) – (R2 *I)?
The voltages Um in the middle of the respective voltage dividers are determined according to the divider control. Have you never heard of voltage dividers? What you wrote above is totally wrong.
