The transformer secondary is now connected to a purely resistive load drawing 50A. Calculate:
a) the total resistance and leakage reactance values referred to the secondary (Rt2 and Xt2),
b) the output voltage,
c) the output power, VA and Vars,
d) the iron loss, primary copper loss and secondary copper loss,
e) the efficiency,
f) the input current in magnitude and phase (wrt the supply voltage).
