Bridge Circuit Equivalent Resistance using Delta-Y Transform

Physics Ninja uses a delta-y transformation to solve for the equivalent resistance of a bridge network. Here's the link to the first video showing how use Kirchhoff's laws to find the equivalent resistance.

I took physics 2 more than two years ago. It’s a good thing to review and learn new tricks, since I love physics so much! Thank you very much! You got a big fan!

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.

Wow. Your enthusiasm towards Physics is really clear in this video. Subscribed!

thank you Sir you are the best!!!

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.

Thank you so much, this helps me a lot!

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 nice u made a video on it though cleared some of my concepts 🙌

very good, thanks for following my comment

[awiterpgamer]

Can you do a video solving the individual current?

[Xplore_Xploit]

I got wrong answer, R Value of all resistors is 15 ohm . what is Req?

[rahulpurohit]

Why am I supposed to do this in my 1st of Btech computer science
Is it the same in other countries

[a.nelprober]

Cool but for bridge why not just do kvl impedance matrix

[EATW]

wye delta more complex bridge network problems solved steps

[sundayamaechi]

Sir please I want to also learn how to solve this using kirchoff rule

[romeocutiyog]

Where comes the other 1/3, when you combine those two series resistor

[mdhimel]

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 sir...i am your student from bangladesh😍😍😍

[salmavian]

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 ??
