Not all solution manuals are created equal. Beware of scanned, fifth-generation PDFs with missing pages or wrong phasors.
Rated secondary current ( I_s = 10,000 / 240 = 41.67 A ). Referred to primary: ( I'_s = I_s / a = 41.67 / 10 = 4.167 A ).
The load power factor is 0.8 lagging, so ( \theta = \cos^-1(0.8) = -36.87^\circ ) (Negative because current lags voltage). [ \vecI'_s = 4.167 \angle -36.87^\circ A ]

If you find a scanned PDF, verify one problem manually before trusting it. Compare the given numerical answer against known correct values (e.g., from your professor or a study buddy).
Summary: The solutions manual is a powerful learning tool when used as a tutor after failure, not as a source before thinking. Focus on understanding the why behind each step, not just the final number.
