Consider a delta connection of resistors and its equivalent star connection as shown below. If all elements of the delta connection are scaled by a factor k, k > 0, the elements of the corresponding star equivalent will be scaled by a factor of
-
- k2
- k
- 1 / k
- √k
Correct Option: B
| Rc = | as Ra is scaled by facts k | |
| Ra + Rb + Rc |
| R'c = | ||
| R'a + Rb + Rc |
| = | = k. | |||
| k(Ra + Rb + Rc) | Ra + Rb + c |
so elements corresponding to star equivalence will be seated by facts k.
