Transformer utilization factor of a center tapped full wave rectifier is equal to ___________

Transformer utilization factor of a center tapped full wave rectifier is equal to ___________ Correct Answer 0.693

Transformer utilization factor is the ratio of DC power supplied to the AC rating of the primary winding. The factor indicated the effectiveness of transformer usage by the rectifier. For a center tapped full wave rectifier, it is equal to 0.81 w.r.t the primary winding, 0.57 w.r.t the secondary winding (double of that of a half wave rectifier) and the average value is 0.69.
