In a two winding transformer with a laminated core, the winding with N1=200 turns is connected to a voltage to produce a flux density in the core B = 1.2 sin 377t. The second winding with N2=400 turns, is left open circuited. The stacking factor of the core is 0.95 i.e., the core occupies 95% of the gross core volume. The gross cross sectional area of the core is 25 cm2 and μr for the core is 10000. The core length lc=90 cm. The rms value of the applied voltage is ___________V.(Neglect primary impedance)151.95 |
