I have some inductors with unknown inductance and I'm looking for a very simple but reliable method to measure its value(doesn't have to be precise or accurate but just get me in the neighborhood).

I was thinking that I could simply using a constant current source to drive the inductor and measure the voltage drop across it then use the formula

L = V/I/(2***Pi***f)

to compute L.

This works in theory but is it pratical? I was thinking of the mains to generate the frequency and about 1mA of current or so... the current acts as a scaling factor that can be used to for small or large inductors... and I suppose one could throw in a resistor to "fine tunning" but I'm mainly want something simple.

Would this work? or is there an easier method(this seems like the easiest but who knows ;)?

Thanks, Jon
