In a two-winding transformer N1 = 2000 and N2 = 500 and the supply voltage V1 = 1200 V. The transformer has winding resistances R1 = 2.0 %u2126 and R2 = 0.125ohm , and leakage reactances X1 = 8.0 and X2 = 0.5ohm . If a resistive load of 12 ohm is connected across the
secondary winding calculate the load voltage V2 and the transformer voltage regulation.
