4- A single phase transformer has 450 Turns on the primary winding If it is connected to a \( 120 \mathrm{~V}, 60 \mathrm{~Hz} \) supply, the no-load current is 1.5 A and the no-load power input is 82 W . Neglect the leakage reactance and winding resist Calculate a) The core loss current b) The magnetizing current. c) The maximum core flux d) The magnetizing admitance, impedance, conductance, and suseeptance of the equivalent circuit
