A delta network has each resistor of value 9Ω. Find the equivalent star network resistors. R23=PR1=993=33Ωcap R sub 23 equals the fraction with

Before diving into the mathematics, it is vital to recognize the visual and structural characteristics of both networks. Star (Y) Configuration

Convert this network into an equivalent Star network with central point N. Calculate the sum of all delta resistances: There is no neutral point in a delta network

For delta→star, always sum all three delta resistors, not just two.

A three-phase circuit is connected in a star configuration with a phase voltage of 230V and a phase current of 10A. Find the equivalent delta-connected circuit.

Before diving into algebraic transformations, it is vital to visualize how the resistors or impedances are connected in both configurations.
