| It is possible to substitute other component values in cases where the specified values are not readily available. The reactance of a component (X<sub>C</sub> or X<sub>L</sub>) scales with frequency. For example if 4.7 mH inductors are available rather than the 47 mH called for all that is needed to do is increase the test frequency from 250 Hz to 2.5 KHz. The same would be true when substituting a 1.0 uF capacitor for the 10.0 uF capacitor specified. | It is possible to substitute other component values in cases where the specified values are not readily available.

| ALICE desktop includes an impedance analyzer / RLC meter which can be used to measure the series resistance (R) and reactance (X). As part of this lab activity it might be informative to use this tool to measure the components R, L and C used to confirm your test results. | ALICE desktop includes an [[university:tools:m1k:alice:desktop-sa-ba-ia-users-guide|Impedance Analyzer]] / RLC meter which can be used to measure the series resistance (R) and reactance (X).
