A two-winding single phase transformer has a voltage regulation of 4.5% at full-load
and unity power-factor. At full-load and 0.80 power-factor lagging load the voltage
regulation will be
(A) 4.5%. (B) less than 4.5%.
(C) more than 4.5%. (D) 4.5% or more than 4.5%.
and unity power-factor. At full-load and 0.80 power-factor lagging load the voltage
regulation will be
(A) 4.5%. (B) less than 4.5%.
(C) more than 4.5%. (D) 4.5% or more than 4.5%.
