Solved Examples Problems On Star-Delta Transformation Or Conversion

Ques:- Find the equivalent resistance between A & B in the given network.

Solution:-

 For the given network, we can easily determine the value of equivalent resistance i.e, R_AB through  Star-Delta conversion.

We have

Above network can also be represent as below:-

Now, I am going to solved this network by using  delta to star conversion as shown in the figure given below:-

For the value of new star connected resistance are finding through direct formula of delta to star conversion,as shown below

So, R_AB / R_equivalent = R₁ + R₂ + R₃ = 4Ω + 3.88Ω + 1.77Ω = 9.65Ω Answer
