2.A n+400-k VA, 2300+n- 230+n-v, 60-hz transformer supplies a0.8 lagging power-factor load whose KVA Is adjustable from no loadto 120 percent rated KVA. The percent resistance, percentreactance, and percent core loss are m+1.56, m+3.16, and m+0.42respectively. For 2 KVA increments of load, tabulate and plot theefficiency of the transformer from no load to 120 percent ratedload. Use Matlab
n=20
m=.2
