An ideal transformer is shown in Figure 4. It is rated at 2500 VA, 160/800 V rms, 50 Hz. It
has 1500 turns of windings on the secondary coil and a secondary voltage V₂ = 720 V rms
supplies a load resistor of RL=240 0.
(a) Calculate the secondary current 12 and the primary current /1.
(b) Calculate the output power P2 and the transformer efficiency n.
(c) Calculate the reflected impedance Z'L seen by the primary source V₁.
