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

1.	Transformer utilization factor of a half wave rectifier is equal to __________(a) 0.267(b) 0.287(c) 0.297(d) 0.256The question was posed to me during an interview.My doubt is from Halfwave Rectifier in chapter Diode Circuit of Analog Circuits
Answer» The correct choice is (b) 0.287 Explanation: 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.
