	Depending on the supply, i would not use the
	word 'loss'.  Specifically, assuming a filtered,
	unregulated supply:
		The no load voltage will be set by the _peak_
		voltage from the transformer.
		The loaded voltage will be set by the _RMS_
		voltage.
	Thus the loaded voltage will be roughly 0.707 times
	the unloaded/no load voltage.
