2.A n+400-k VA, 2300+n- 230+n-v, 60-hz transformer supplies a 0.8 lagging power-factor load whose KVA Is adjustable from no load to 120 percent rated KVA. The percent resistance, percent reactance, and percent core loss are m+1.56, m+3.16, and m+0.42 respectively. For 2 KVA increments of load, tabulate and plot the efficiency of the transformer from no load to 120 percent rated load. Use Matlab n=20 m=.2
