SUMMARY

This discussion focuses on measuring inductors and their voltage reduction capabilities in RLC circuits. The primary method for measuring an inductor's value is using an LCR meter, which applies an AC waveform and measures the resulting current. Alternatively, one can use a signal generator, resistor, and oscilloscope to determine inductance by observing a 45-degree phase shift in a resistor-inductor series circuit. Inductors can reduce voltage through their reactive impedance and associated DC resistance (DCR), which contributes to voltage drops in both AC and DC applications.

Welcome to the PF. There are a number of ways to measure the value of an inductor. The simplest, of course, is to us some instrument like an LCR meter. Those instruments impress an AC waveform (typically 1kHz or 10kHz or 100kHz) across the inductor, and measure the resulting current.

If you don't have an LCR meter or other AC impedance-measuring device, you can do it youself with a signal generator, a resistor and an oscilloscope. Use the fact that you will get a 45 degree phase shift through the resistor-inductor series combination when the reactance of the inductor equals the value of the resistor. Are you familiar with how the reactance of the inductor varies with frequency?

Can an Inductor reduce voltage

Yes, in several ways. Here is some basic info on RLC circuits:

http://en.wikipedia.org/wiki/RLC_circuits

An inductor has a reactive impedance, which can interact with other impedances in a circuit and provide an AC voltage drop. A real inductor also has an associated DC resistance (DCR), which will act like any other resistor and provide a DC and AC voltage drop when a current flows through it. You usually will chose an inductor that has a small DCR compared to its reactive impedance at the frequencies of interest, though. Make sense?
 

Thread 'uA709 op amp compensation'

Most likely this can only be answered by an "old timer". I am making measurements on an uA709 op amp (metal can). I would like to calculate the frequency rolloff curves (I can measure them). I assume the compensation is via the miller effect. To do the calculations I would need to know the gain of the transistors and the effective resistance seen at the compensation terminals, not including the values I put there. Anyone know those values?
