any help would be much appreciated(adsbygoogle = window.adsbygoogle || []).push({});

i am trying to calculate the inductance and impedance of a unknown air cored inductor. over a set frequency range (1600hz - 2700hz in 100hz increments) using a series RL circuit

tools

scope

multimeter

frequence generator

Amplifier

1ohm 100W metal clad resistor(1.07ohms under test)

what i have done so far is

frequency generator is set at 1600hz

the output of a frequency generator is connected to the input of the amplifier

the output of the amplifier is used as the power-source

the positive terminal of the amplifier goes to side a of the inductor, side b of the inductor is connected to side a of the resistor, then side b of the resistor is connected to the negative terminal of the amplifier (if this is unclear please see the attached photo)

as a table of data i have (for this i am using the 1600hz information)

frequency = 1600hz

resistor = 1.07Ohms

voltage across the resistor = 0.84V

voltage across the inductor (voltage from the negative terminal of the amplifier to the inductor terminal) = V1-V2 = 0.19V

using this information how do i calculate the inductance
