I am a newbie at electronics and was hoping I could find some help. I have a coil with a removable iron core, photo for which is given above. I tried to find L1 or the inductance of the coil. I was using the circuit shown in the diagram and a cheap multimeter. I tried applying AC and DC voltage to it. I was wanting to find the voltage drop in R1 so I can use it to find XL or the Inductive reactance, which I would use to find L1. But I am not getting any voltage drop in the resistor across points AB (my multimeter might not be good enough to measure a really . Both in AC and DC. Is it because the coil I am using will have such a high L value that all the voltage is dropping across the coil? Is there anyway of doing this without an oscilloscope, function generator and such tools?
The easiest way to determine an inductance is by using an RLC measuring bridge. Since this isn't a very cheap solution, most of the time the step response of an RL circuit is used in combination with an oscilloscope.
