Delta to Star Conversion:
Consider a three terminal network in which the resistors are connected in the form ∆.
Such a network is known as delta network.
Let the resistor values are R12, R23 and R31. Now we find its equivalent Y-network such that both the circuits are identical as far as the terminals 1, 2 and 3 are concerned. Let the resistor values are R1, R2 and R3.
