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 ;)?
