Hallo, ich habe folgende Schaltung. Soll nun die Gesamtwiderstände zwischewn A und B ausrechnen. Der Widerstand R3 und R4 sind parallel geschaltet. Wie ist der Ersatzwiderstand R34 und R1 geschaltet ? Parallel oder in Reihe ?
Und was verstehe ich unter “zwischen den Punkten C und D” Ist es letzendlich nicht das selbe wie bei Punkt A und B ?
Danke

The question came up in my company and since I'm not really good at electronics but would like to learn a bit, I would like to understand what I have to do. I have a broken lightbulb. I already replaced it, thinking it was the fault of the lightbulb itself. But it turns out the…

Hello dear com Why does the railway have a 16 2/3 Hz network and not a 50 Hz network like in a normal household? What advantages does this bring? Or what disadvantages would the 50 Hz system have? I'd be interested to know.
Hi, welche Akku Luftpumpe ist zu empfehlen ?
Between A and B you have:
Between C and D, I would recommend you re-record the plan. Then (thank you) make a color A up to the first resistors, then a color B from this resistor to the next. All that depends on the same color is parallel, everything else in series.
Thank you. But I still don’t understand how to calculate it between C and D. From where to where should I record something?
Go from C, then the branch splits into R1 and R2. The two branches are parallel (Preview: Not R1 and R2 are directly viewed as a parallel circuit).
Behind R1 comes R3 and R4 at the same branch, i.e. they are parallel. R3 and R4 then hang on D, just like R2. Say, R3, R4 and R2 are parallel to one another.
But now you have the entire Ast R1 + R3 + R4 parallel to R2, i.e. when you clean the “from behind”, you first receive a parallel R3 + R4, which is in series with R1. This replacement resistor R134 is parallel to R2.
The resistors between A and B are arranged differently than between C and D.
If you mark the potentials in color, you will also notice that B and D have the same potential (green in the drawing).
It also makes sense to redraw the drawing in order to better understand the arrangement of the resistors between C and D.
Solution route AB
R1 and R2 are in series:
R3 and R4 are parallel to one another:
R12 and R34 are also parallel to one another:
Solution path CD
R34 are parallel to one another:
R1 is in series with R34:
R2 is parallel to R134:
