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 resistance at node Z is?
(a) RyRx/(Rx+Ry+Rz)
(b) RyRx/(Rx+Ry+Rz)
(c) RzRy/(Rx+Ry+Rz)
(d) (Rz+Rx)/(Rx+Ry+Rz)
I have been asked this question by my school teacher while I was bunking the class.
My enquiry is from Star-Delta Transformation in chapter Useful Theorems in Circuit Analysis of Network Theory
