a. C. d. c. b. نه نن د به a. b. C. e. PPPPP C. d. d. C. fખું છું e. 5. From the measurements of the short circuit test and open circuit test of the single-phase transformer, we can calculate the core losses only we can calculate the winding losses only we can calculate the full load efficiency if the full load current is given only we can calculate the voltage regulation if the per unit loading is given only non of the above a. 7- Two-wattmeter b. e. 6- For the single-phase circuit with a capacitive load the maximum instantaneous power is half of the average power double the average power 0.707 of the average power 1.414 of the average power non of the above 9- In a star connection of a balanced inductive load 8- Three-wattmeter method can be used in a star connected load only a star connected load with a neutral wire only a delta connected load only items "a", "b" and "c" items "a" and "b" the line voltage is shifted from the phase current by 30⁰ the line voltage leads the phase current by 300+the angle of the power factor the line voltage lags the phase current by 30° the angle of the power factor d. the line voltage is in phase with the phase current non of the above method can be used in a balanced delta connected load only a balanced star connected load without a neutral wire only a balanced star connected load with a neutral wire only items "a", "b" and "e" are correct item "b" and "e" are correct
