How to Identify or Measure Inductance? Answered
I am gathering the parts for an ible, but I am short one part: a 12mH inductor.
I can spot some inductors in electronic garbage - the wire coiled around a ferrite loop - but there are also solid state inductors. Plus, the inductors are not usually labelled with their values.
How can I measure the inductance of an inductor with a volt-meter and an ammeter, but without access to a sine-wave generator?
Is there some simple trick that would get me "close enough" to the true value? What would be really useful (but probably doesn't exist) is a chart or formula where you plug in the size of the core and the number of turns around it and out pops the inductance value.
