equivalent resistance

finding the equivalent resistance delta

Can anyone help me find the Equivalent Resistance of this particular circuits?
I attached it as a file.
Thanks.

Change the upper or lower delta to star and then add the resistors in parallel and siries.

The equation for Equivalent resistant is attached. for the resistor values in your document:

RS=2k
R1=10
R2=200
R3=20
R4=100
R5=50

Req = 2k+26.6187 = 2026.6187 Ohms;

Req =2027 ohms

you can calculate the equivalent resistance by using Delta to Star method of R1 R2 and R5. Afterthat, you will get series and pallell resistances easily and you find get equilent resistance of the circuit.

If you transform R5 into 2 dependent current sources ( I=V/R5, where one terminal connect to the ground and the other terminal connect to the node), you can solve the equivalent resistance without knowing the "delta" transformation.
