A single-phase transformer of 3 kVA, 60 Hz, hasa voltage ratio on open circuit of 240 / 120 V.The primary and secondary resistances are 0.25 Ωand 0.05 Ω respectively, the corresponding leakagereactance being 0.75 Ω and 0.18Ω. The transformer delivers current to the load at a 0.9power factor lagging.
