a) An ideal single-phase two-winding transformer with turns ratio a, = N1/N2 is con nected with a series impedance Z across winding 2. If one wants to replace Zz, with a series impedance Z across winding 1 and keep the terminal behavior of the two cir cuits to be identical, find Z, in terms of Z. (b) Would the above result be true if instead of a series impedance there is a shunt impedance? (c) Can one refer a ladder network on the secondary (2) side to the primary (1) side simply by multiplying every impendance by af?
