Hi all, I feel really stupid for asking this, but something is whispering in my ear that I'm wrong, so I would appreciate a second (third, fourth, etc...) opinion.
I'll make a coil (air core inductor) from a coil winding formula and would like to measure it's inductance.
My plan is to place the unknown coil in series with a known, non-inductive (carbon comp) resistor, then apply a sinusoidal signal of known F from my function generator. Then measure the signal amplitude across the coil and resistor (oscilloscope) and derive the "resistance" (inductive reactance) of the coil, finally plugging the value into "L=Xl/2PIF" and get the inductance. The inductance will be in the tens of uH, so the scope probe and test leads will not influence the result (much).
It seems right to me, but something says I'm missing something. Comments please?
