Transformer utilization factor of a centre tapped full wave rectifier

1.	Transformer utilization factor of a centre tapped full wave rectifier is_________(a) 0.623(b) 0.678(c) 0.693(d) 0.625I have been asked this question in a national level competition.This interesting question is from Full-wave Rectifier topic in section Application of Diodes of Electronic Devices & Circuits
Answer» Right option is (C) 0.693 The best explanation: Transformer utilisation factor is the RATIO of AC power delivered to load to the DC power rating. This factor INDICATES EFFECTIVENESS of transformer usage by rectifier. For a half wave rectifier, it’s low and EQUAL to 0.693.
