Are these inductors?
If so, can anybody estimate their ratings? Or is there a way I can measure them? I'm looking for something around a 4mH inductor to use in "Simplest Ever DC-DC Boost 12v to 73v" instructable by "pyrohaz". Also, are these potential inductors the same as the ones found in CFL light bulbs? And one more thing, why does the small one have 4 wires coming out, the medium one has 2 wires, and the big one has 10?
