Transformer utilization factor of a half wave rectifier is equal to __________

Transformer utilization factor of a half wave rectifier is equal to __________ Correct Answer 0.287

Transformer utilization factor is the ratio of DC output power to the AC rating of the secondary winding. AC rating is the product of RMS voltage across winding and RMS current through the winding, expressed in volt-amp. This factor indicates the effectiveness of transformer usage by a rectifier. For half wave rectifier it is low and equal to 0.287.
