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?a) Rac/(Rab+Rbc+Rca)b) Rab/(Rab+Rbc+Rca)c) Rbc*Rab/(Rab+Rbc+Rca)d) Rab/(Rab+Rbc+Rc |
A. | Rac/(Rab+Rbc+Rca) |
B. | Rab/(Rab+Rbc+Rca) |
C. | Rbc*Rab/(Rab+Rbc+Rca) |
D. | Rab/(Rab+Rbc+Rca) |
Answer» D. Rab/(Rab+Rbc+Rca) | |
