Al,

An inductor (coil) is almost pure inductance (hence the name) & very little
resistance, thus on dc it presents a low resistance (as you've indicated).
Thus if there is minimal load there will be minimal voltage drop across it
(what's the dc current?).  What is the application the inductor is being
used for?

Also, are you sure its 10uH and not 10 mH.

Regards



Kevin
