or, each Example: If each arms of delta network is scaled by a factor of K, then by what factor arms of star network will be scaled. (B) (D) K K (A) (C) 1/K 1/K2
here is the explanation. each side of star is also scaled by k. see the expression of "R12", In its expression, if you multiply each resistance in RHS by "k", then k^2 will come ou...
