[ R_A = \fracR_AB \times R_CAR_AB + R_BC + R_CA ]
Since it is balanced (all delta resistors equal), the star resistors are equal. [ R_star = \fracR_delta3 = \frac93 = 3\Omega ] Each star resistor = 3Ω. star delta transformation problems and solutions pdf
In a balanced network, no need for complex arithmetic. Problem 2: Star to Delta Conversion (Unbalanced) Question: A star network has R_A = 10Ω, R_B = 20Ω, R_C = 30Ω. Find the equivalent delta resistors between A & B. [ R_A = \fracR_AB \times R_CAR_AB + R_BC
