5Ω, Rc=4.67Ω A. Ra=4Ω, Rb=4.30Ω, Rc=4.66Ω B. Ra=3Ω, Rb=4Ω, Rc

5-rc-4-67-a-ra-4-rb-4-30-rc-4-66-b-ra-3-rb-4-rc

5Ω, Rc=4.67Ω

A. Ra=4Ω, Rb=4.30Ω, Rc=4.66Ω

B. Ra=3Ω, Rb=4Ω, Rc =5Ω

C. Ra=5.2Ω, Rb=4.2Ω, Rc =4.89Ω

I have been asked this question in an interview for internship.

The doubt is from Measuring Resistance the Wheatstone Bridge and Delta-to-Wye (Pi-to-Tee) Equivalent Circuits topic in portion Simple Resistive Circuits of Electric Circuits

Correct choice is B. Ra=3Ω, Rb=4Ω, Rc =5Ω

To explain: By using the standard formulae the delta circuit can be converted into star circuit.
