A single-phase transformer is rated at 10 kVA, 240/100 V. When the secondary terminals are open-circuited and the primary winding is supplied at normal voltage, the input current is 2.6 A at a power factor of 0.3 lag. When the secondary terminals are short-circuited, a voltage of 18 V applied to the primary causes the full-load current to flow in the secondary, the power input to the primary being 240 W. Calculate (a) the regulation (b) the efficiency of the...
