Transformer utilization factor

The transformer utilization factor (TUF) of a rectifier circuit is defined as the ratio of the DC power available at the load resistor to the AC rating of the secondary coil of a transformer.[1][2]

$T.U.F={\frac {P_{odc}}{V_{A}\ rating\ of\ transformer}}$

The $VA$ rating of the transformer can be defined as: $V_{A}=V_{r.m.s}{\dot {I}}_{r.m.s}(For\ secondary\ coil.)$ TRANSFORMER utilization factor for half wave rectifier is .287 or .3.
