In physics lab we were using a signal generator with sine wave to find the frequency of a circuit quite precisely. Unfortunately, we had trouble and when checked with a circuit with purely resistive impedance, voltage changed with the frequency of the sine wave.(adsbygoogle = window.adsbygoogle || []).push({});

The signal generator is rather ancient, but my professor stated it worked the previous semester. Is this often something a simple dusting could fix?
