| An interesting question |
| << < (3/6) > >> |
| Sarvesaa:
Since I am a high schooler I found it interesting. |
| armandine2:
You might find the following interesting too and worth some time to consider - it is puzzling to me, but beginning to make some sense. ... known in my copy of Tietze and Schenk Electronic Circuits as a double centre tap full wave but also Dual Polarity Full-Wave Centre Tap https://forum.allaboutcircuits.com/threads/dual-polarity-full-wave-center-tap-rectifier.30066/ |

I have attached the circuit down. --- End quote --- I had a similar problem in class recently, and another approach is wye-delta transformation. |
| TimFox:
The wye-delta transformation and the series-parallel impedance transformation are extremely powerful methods for circuit analysis. I always had a list of these transformation equations prominently on the bulletin board next to my desk before retiring. |
| EPAIII:
Yes, once you realize that, the problem is a trivial exercise in series and parallel resistor combinations. Then Ohm's law and done. Now, substitute the values of 1, 2, 3, 5, 7, and 11 Ohms for each of the resistors, any order you want, and then solve it. That will separate the men from the boys. --- Quote from: eugene on July 26, 2022, 03:30:26 pm --- --- Quote from: TimFox on July 26, 2022, 03:20:59 pm ---Since, by inspection, there is no voltage across the "diagonal" 5 ohm resistor, and therefore no current through it, the solution is straightforward. --- End quote --- Which I assume is the real reason for the question: to see who does and does not see the symmetry. --- End quote --- |
