Hi John,
I figured it out now; I know how you got the 5 volts! I was just
overthinking things.
I figured out my acceptable reflected resistance, then my turns ratio ,
then my current and voltage - rather simple really. My only problem now is I
dont have any sensitive( microamp range) meters around . The most sensitive
one I have is a 0-1 ma .I can make it work ; I can also calibrate it to work
with a 0-200 ua meter and just use the 0-200 ua scale on my multimeter for
now.
Thanks again
Rick
