Hi. This is a question from my lab. I have a series of measurements of the voltage drop across a resistor for various frequencies with a constant voltage source in an LR series circuit. From these measurements I am supposed to calculate the value of the inductance "L". How can I do this?

For homework help you have to show some work to get some help.

What is the reactance, XL as a function of frequency?

XL = [tex]2*pi*f*L[/tex]

OK... are you going to solve for L using geometry or the equations for complex impedence?
