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 = 1.2sin 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 |
