Star to Delta Conversion in tamil

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. Thank you for watching
