Detailed Solution
Download Solution PDFThe correct answer is option 3):(6 Ω, 18 Ω, 12 Ω)
Concept:
Star-to-delta conversion
RA = R1 + R2 +
RB = R1 + R3 +
RC = R2 + R3 +
Calculation:
Given
RA = R1 + R2 +
= 2 + 3 +
RB = R1 + R3 +
= 6 +2 +
= 6 +2 + 4 = 12
R3 = R2 + R3 +
= 3 + 6 +
= 18
hence option 3 is correct
