Energy conversions matlab code needed A 110 kVA 2200220 V 60

A 1-,10 kVA, 2200/220 V, 60 Hz transformer has the following characteristics: No-load core loss 100 w Full-load copper loss =215 w Write a computer program to study the variation of efficiency with output kVA load and load power factor. The program should a) Yield the results in a tabular form showing per-unit kVA load (ie, a) Yield the results in a tabular form showing per-unit kVA load (i.e. X), and efficiency for a range of power factors 1.0, 0.8,0.6, 0.4, and 0.2. | (P.F. = 1.0) | (Pf.:0.8) | (P.F. = 0.6) | (P.F. = 0.4) | (P.F. =0.2) 0 0.05 0.1
