If a resistor Rx is connected between nodes X and Y, Ry between X and Y, Rz between Y and Z to form a delta connection, then after transformation to star, the resistor at node X is?
(a) RxRy/(Rx+Ry+Rz)
(b) RxRz/(Rx+Ry+Rz)
(c) RzRy/(Rx+Ry+Rz)
(d) (Rx+Ry)/(Rx+Ry+Rz)
I got this question in quiz.
This interesting question is from Star-Delta Transformation topic in portion Useful Theorems in Circuit Analysis of Network Theory
