This is a case of balanced bridge . All resistances are of value 2 ohm . So equivalent resistance between a and b is 2 ohm .

[deepak__saini]

Sir what will be the answer of z4 .
I mean will there be any value of z4 for the bridge to be balanced?
Please reply sir...

We can use vertical line symmetry right ?

[ankitg]

What is the correct answer. How to clip impedance angle of -120 deg within the range ?

[aynunnazreen]

Sir .y can't we do this problem using vertical plane of symmetry

[hydra]

Sir ac circuit analysis, transient, steady state

[gautamgupta]

how do i find resistance if bridge isnt balanced

[rishabhbahoria]

sir HW problems webpage is not available !

[razzstanley]

From terminal b, ((2+2//2)+2)//2
Req=5/4=1.25 why this is not correct?

[raveenaravi]

Web page is not available for hw prblm sir..

[avunooritagore]

Power systems was stopped at 26lecture complete it sir

[wilbowednesday]

HW: Another balanced bridge network, therefore Rab= 2 ohms

[vijayapriyas]

Answer is 5/2=2.5 ohms, am I right sir?
