The time constant is L/R.One long while ago I bought a capacitance/ inductance meter. I had a thought how to do this for the DIY user. It starts off with this premise:
does anyone see any obvious flaws with this idea?
I will come up with other ideas for this project and post them here.
any chance you could get a schematic?A while back I came across a very simple circuit with a bistable multivibrator, where the feedback on one side was the inductor. The inductance is inversely proportional to the frequency of oscillation. Same idea.
See the link:I'm not sure of the TC=L/R, As the resistance increases the TC goes down.
Here are a couple of circuits with voltage or frequency output for the inductance values from a few hundred uH to 10mH.any chance you could get a schematic?
