Question: Rab is the resistance between the terminals A and B, Rbc between B and C and Rca between C and A. These 3 resistors are connected in delta connection. After transforming to star, the resistance at B will be?

Options

A : Rac/(Rab+Rbc+Rca)

B : Rab/(Rab+Rbc+Rca)

C : Rbc*Rab/(Rab+Rbc+Rca)

D : Rab/(Rab+Rbc+Rca)
