My professor started throwing bridge circuits at us, having us solve for equivalent resistance as well as the current through each resistor, without explaining beforehand that normal series and parallel reduction rules don't really apply to the bridge. The class average on the exam covering this topic was a 27%... Honestly it's quite frustrating finding out later that you're missing a very important piece of the puzzle.

Didn't know delta-Y conversions could be used other than in three-phase circuits. Incredibly useful and quick to solve these bridge circuits. Also even easier, in 3-phase circuits if the delta load is balanced (all resistors/impedances have the same value, just like in this example) R1,R2,R3 always equal the delta resistor (in this case 1ohm) divided by three.

Woah are u serious you had never heard of this before.... I am in class 9 and I knew about this albeit through the preparation of physics olympiad. Yes It is extremely useful for solving circuit sums and a modified version can also be applied to capacitors and inductors.... But its by far the coolest hack of solving unbalanced Wheatstone bridges..... nice u made a video on it though cleared some of my concepts 🙌

Rules of symmetry don't apply here ?i think i can just use laws of symmetry instead of kirshoff and y delta or i can't do it because resistors aren't equal ? , second thing is that i get ur method but generally how will the current flow exactly in the circuit with numbers how will it pass ??

Where comes the other 1/3, when you combine those two series resistor
@PhysicsNinja
4 жыл бұрын
The 1/3 factor comes from he transformation of the delta to y network of resistors. I have a video on this. I also have a video where I don’t use any simplifications. I only apply Kirchhoffs laws to some it.

I agree with you. It’s 6/3 for the two resistors. And he added 1/3 again 🙁?? Where from the 1/3

Sir,how can i solve this circuit as a mixed circuit??don' use any theorem or delta-star how can i solv e it as a series parralel circuit??plz help me Or How to rearrange a complex circuit??is that any method,?if it has a method plz upload a video for that......tnx sir...i am your student from bangladesh😍😍😍

Can't solve this circuit as a series parallel. There are many other videos handling rearranging complex circuits.

You have to use the 2 laws of Kirchoff. It leads to a system of equations that can be solved to find pretty much everything, including the total current flowing through. So the Req = V/I

Were you able to solve this a series-parallel? Our lab activity asks us to it too and i don't know what to do.
