    If L/R (= 1 time constant = 63% of current rise)  either in the primary
circuit or the secondary circuit, was a small enough period of time, then if
the operating frequency of the coil were high enough, it is conceivable that
the time it takes for 1/4  cycle of the sine wave would be less than one
time constant, so you couldn't possibly transfer more than 63% of available
energy (ideally it seems to me, that this time should equal 5 time
