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

V = L * dI/dT
But there's probably no such thing as a perfect inductor,
and most practical coils have finite DC resistance, and
you didn't tell us how much or how much current flows.
Does sci.electronics.basics still exist?
