When converting from Delta to Star, the equivalent Star resistances are smaller than the Delta resistances. The general rule is:

"The resistance of an arm of the Star is the product of the two adjacent Delta resistances divided by the sum of all three Delta resistances." A well-structured PDF is invaluable for exam preparation

If $R_AB, R_BC, R_CA$ are the Delta resistances:

Delta resistors: R_AB = 6Ω, R_BC = 12Ω, R_CA = 18Ω. Convert to star. Many universities also provide free problem sets under

Solution:

R₁ = (R_CA × R_AB) / (R_AB + R_BC + R_CA) = (18×6)/(6+12+18) = 108/36 = 3Ω
R₂ = (R_AB × R_BC) / (R_AB + R_BC + R_CA) = (6×12)/36 = 72/36 = 2Ω
R₃ = (R_BC × R_CA) / (R_AB + R_BC + R_CA) = (12×18)/36 = 216/36 = 6Ω
