a Just a quick question.
a Please I need clarification on this:
a Would a voltage of say 12volts running through a coil of 10 uh be lower
a after the coil?.
a Does a coil infact drop the voltage?
a Thanks

You should really study the difference in behaviour between DC and AC to
properly understand the effect you are trying to measure. As previous
posters have pointed out the DC resistance of such a coil is so low that a
simple multimeter is unlikely to provide a sensible reading as it is using
DC. The resistance you have "measured" is likely to mostly be the contact
resistance of the probes. To answer your question though, the DC volts
before and after the coil will be pretty well the same. The coil only
inteferes with the voltage for a very brief time, as the magnetic field
builds up around the coil. An inductive component like this, is an AC
animal.
